feat: compile to JS for npm, release system, full changelog

- Add tsc build step (tsconfig.build.json) so npm package ships
  compiled JS instead of raw TypeScript requiring tsx at runtime
- Update qmd wrapper and daemon spawn to use dist/qmd.js in
  production while keeping tsx for development
- Add self-installing pre-push hook validating v* tag pushes:
  package.json version match, changelog entry, CI status
- Add release.sh script that renames [Unreleased] to versioned
  entry, bumps package.json, commits, and tags
- Add extract-changelog.sh for cumulative GitHub release notes
- Update publish workflow with build step and GitHub release creation
- Flesh out CHANGELOG.md with full history from 0.1.0 through 1.0.0
  in Keep-a-Changelog format with PR/contributor attributions
- Add release standards and changelog guidelines to CLAUDE.md

 # Changelog
 
-All notable changes to QMD will be documented in this file.
+## [Unreleased]
 
 ## [1.0.0] - 2026-02-15
 
-### Node.js Compatibility
+QMD now runs on both Node.js and Bun, with up to 2.7x faster reranking
+through parallel GPU contexts. GPU auto-detection replaces the unreliable
+`gpu: "auto"` with explicit CUDA/Metal/Vulkan probing.
 
-QMD now runs on both **Node.js (>=22)** and **Bun**. Install with `npm install -g @tobilu/qmd` or `bun install -g @tobilu/qmd` — your choice. The `qmd` wrapper auto-detects Node.js via `tsx` and works out of the box with mise, asdf, nvm, and Homebrew installs.
+### Changes
 
-### Performance
+- Runtime: support Node.js (>=22) alongside Bun via a cross-runtime SQLite
-
+  abstraction layer (`src/db.ts`). `bun:sqlite` on Bun, `better-sqlite3` on
-- **Parallel embedding & reranking** — multiple contexts split work across CPU cores (or VRAM on GPU), delivering up to **2.7x faster reranking** and significantly faster embedding on multi-core machines
+  Node. The `qmd` wrapper auto-detects a suitable Node.js install via PATH,
-- **Flash attention** — ~20% less VRAM per reranking context, enabling more parallel contexts on GPU
+  then falls back to mise, asdf, nvm, and Homebrew locations.
-- **Right-sized contexts** — reranker context dropped from 40960 to 2048 tokens (17x less memory), since chunks are capped at ~900 tokens
+- Performance: parallel embedding & reranking via multiple LlamaContext
-- **Adaptive parallelism** — automatically scales context count based on available VRAM (GPU) or CPU math cores
+  instances — up to 2.7x faster on multi-core machines.
-- **CPU thread splitting** — each context runs on its own cores for true parallelism instead of contending on a single context
+- Performance: flash attention for ~20% less VRAM per reranking context,
-
+  enabling more parallel contexts on GPU.
-### GPU Auto-Detection
+- Performance: right-sized reranker context (40960 → 2048 tokens, 17x less
-
+  memory) since chunks are capped at ~900 tokens.
-- Probes for CUDA, Metal, and Vulkan at startup — uses the best available backend
+- Performance: adaptive parallelism — context count computed from available
-- Falls back gracefully to CPU with a warning if GPU init fails
+  VRAM (GPU) or CPU math cores rather than hardcoded.
-- `qmd status` now shows device info (GPU type, VRAM usage)
+- GPU: probe for CUDA, Metal, Vulkan explicitly at startup instead of
-
+  relying on node-llama-cpp's `gpu: "auto"`. `qmd status` shows device info.
-### Test Suite
+- Tests: reorganized into flat `test/` directory with vitest for Node.js and
-
+  bun test for Bun. New `eval-bm25` and `store.helpers.unit` suites.
-- Tests split into `src/*.test.ts` (unit), `src/models/*.test.ts` (model), and `src/integration/*.test.ts` (CLI/integration)
-- Vitest config for Node.js; bun test still works for Bun
-- New `eval-bm25` and `store.helpers.unit` test suites
 
 ### Fixes
 
-- Prevent VRAM waste from duplicate context creation during concurrent loads
+- Prevent VRAM waste from duplicate context creation during concurrent
-- Collection-aware FTS filtering for scoped keyword search
+  `embedBatch` calls — initialization lock now covers the full path.
-
+- Collection-aware FTS filtering so scoped keyword search actually restricts
----
+  results to the requested collection.
 
 ## [0.9.0] - 2026-02-15
 
-Initial public release.
+First published release on npm as `@tobilu/qmd`. MCP HTTP transport with
+daemon mode cuts warm query latency from ~16s to ~10s by keeping models
+loaded between requests.
 
-### Features
+### Changes
 
-- **Hybrid search pipeline** — BM25 full-text + vector similarity + LLM reranking with Reciprocal Rank Fusion
+- MCP: HTTP transport with daemon lifecycle — `qmd mcp --http --daemon`
-- **Smart chunking** — scored markdown break points keep sections, paragraphs, and code blocks intact (~900 tokens/chunk, 15% overlap)
+  starts a background server, `qmd mcp stop` shuts it down. Models stay warm
-- **Query expansion** — fine-tuned Qwen3 1.7B model generates search variations for better recall
+  in VRAM between queries. #149 (thanks @igrigorik)
-- **Cross-encoder reranking** — Qwen3-Reranker scores candidates with position-aware blending
+- Search: type-routed query expansion preserves lex/vec/hyde type info and
-- **Vector embeddings** — EmbeddingGemma 300M via node-llama-cpp, all on-device
+  routes to the appropriate backend. Eliminates ~4 wasted backend calls per
-- **MCP server** — stdio and HTTP transports for Claude Desktop, Claude Code, and any MCP client
+  query (10.0 → 6.0 calls, 1278ms → 549ms). #149 (thanks @igrigorik)
-- **Collection management** — index multiple directories with glob patterns
+- Search: unified pipeline — extracted `hybridQuery()` and
-- **Context annotations** — add descriptions to collections and paths for richer search
+  `vectorSearchQuery()` to `store.ts` so CLI and MCP share identical logic.
-- **Document IDs** — 6-char content hash for stable references across re-indexes
+  Fixes a class of bugs where results differed between the two. #149 (thanks
-- **Multi-get** — retrieve multiple documents by glob pattern, comma list, or docids
+  @igrigorik)
-- **Multiple output formats** — JSON, CSV, Markdown, XML, files list
+- MCP: dynamic instructions generated at startup from actual index state —
-- **Claude Code plugin** — inline status checks and MCP integration
+  LLMs see collection names, doc counts, and content descriptions. #149
+  (thanks @igrigorik)
+- MCP: tool renames (vsearch → vector_search, query → deep_search) with
+  rewritten descriptions for better tool selection. #149 (thanks @igrigorik)
+- Integration: Claude Code plugin with inline status checks and MCP
+  integration. #99 (thanks @galligan)
 
 ### Fixes
 
-- Handle dense content (code) that tokenizes beyond expected chunk size
+- BM25 score normalization — formula was inverted (`1/(1+|x|)` instead of
-- Proper cleanup of Metal GPU resources
+  `|x|/(1+|x|)`), so strong matches scored *lowest*. Broke `--min-score`
-- SQLite-vec readiness verification after extension load
+  filtering and made the "strong signal" short-circuit dead code. #76 (thanks
-- Reactivate deactivated documents on re-index
+  @dgilperez)
-- BM25 score normalization with Math.abs
+- Normalize Unicode paths to NFC for macOS compatibility. #82 (thanks
-- Bun UTF-8 path corruption workaround
+  @c-stoeckl)
+- Handle dense content (code) that tokenizes beyond expected chunk size.
+- Proper cleanup of Metal GPU resources on process exit.
+- SQLite-vec readiness verification after extension load.
+- Reactivate deactivated documents on re-index instead of creating duplicates.
+- Bun UTF-8 path corruption workaround for non-ASCII filenames.
+- Disable following symlinks in glob.scan to avoid infinite loops.
 
+## [0.8.0] - 2026-01-28
+
+Fine-tuned query expansion model trained with GRPO replaces the stock Qwen3
+0.6B. The training pipeline scores expansions on named entity preservation,
+format compliance, and diversity — producing noticeably better lexical
+variations and HyDE documents.
+
+### Changes
+
+- LLM: deploy GRPO-trained (Group Relative Policy Optimization) query
+  expansion model, hosted on HuggingFace and auto-downloaded on first use.
+  Better preservation of proper nouns and technical terms in expansions.
+- LLM: `/only:lex` mode for single-type expansions — useful when you know
+  which search backend will help.
+- LLM: HyDE output moved to first position so vector search can start
+  embedding while other expansions generate.
+- LLM: session lifecycle management via `withLLMSession()` pattern — ensures
+  cleanup even on failure, similar to database transactions.
+- Integration: org-mode title extraction support. #50 (thanks @sh54)
+- Integration: SQLite extension loading in Nix devshell. #48 (thanks @sh54)
+- Integration: AI agent discovery via skills.sh. #64 (thanks @Algiras)
+
+### Fixes
+
+- Use sequential embedding on CPU-only systems — parallel contexts caused a
+  race condition where contexts competed for CPU cores, making things slower.
+  #54 (thanks @freeman-jiang)
+- Fix `collectionName` column in vector search SQL (was still using old
+  `collectionId` from before YAML migration). #61 (thanks @jdvmi00)
+- Fix Qwen3 sampling params to prevent repetition loops — stock
+  temperature/top-p caused occasional infinite repeat patterns.
+- Add `--index` option to CLI argument parser (was documented but not wired
+  up). #84 (thanks @Tritlo)
+- Fix DisposedError during slow batch embedding. #41 (thanks @wuhup)
+
+## [0.7.0] - 2026-01-09
+
+First community contributions. The project gained external contributors,
+surfacing bugs that only appear in diverse environments — Homebrew sqlite-vec
+paths, case-sensitive model filenames, and sqlite-vec JOIN incompatibilities.
+
+### Changes
+
+- Indexing: native `realpathSync()` replaces `readlink -f` subprocess spawn
+  per file. On a 5000-file collection this eliminates 5000 shell spawns,
+  ~15% faster. #8 (thanks @burke)
+- Indexing: single-pass tokenization — chunking algorithm tokenized each
+  document twice (count then split); now tokenizes once and reuses. #9
+  (thanks @burke)
+
+### Fixes
+
+- Fix `vsearch` and `query` hanging — sqlite-vec's virtual table doesn't
+  support the JOIN pattern used; rewrote to subquery. #23 (thanks @mbrendan)
+- Fix MCP server exiting immediately after startup — process had no active
+  handles keeping the event loop alive. #29 (thanks @mostlydev)
+- Fix collection filter SQL to properly restrict vector search results.
+- Support non-ASCII filenames in collection filter.
+- Skip empty files during indexing instead of crashing on zero-length content.
+- Fix case sensitivity in Qwen3 model filename resolution. #15 (thanks
+  @gavrix)
+- Fix sqlite-vec loading on macOS with Homebrew (`BREW_PREFIX` detection).
+  #42 (thanks @komsit37)
+- Fix Nix flake to use correct `src/qmd.ts` path. #7 (thanks @burke)
+- Fix docid lookup with quotes support in get command. #36 (thanks
+  @JoshuaLelon)
+- Fix query expansion model size in documentation. #38 (thanks @odysseus0)
+
+## [0.6.0] - 2025-12-28
+
+Replaced Ollama HTTP API with node-llama-cpp for all LLM operations. Ollama
+adds convenience but also a running server dependency. node-llama-cpp loads
+GGUF models directly in-process — zero external dependencies. Models
+auto-download from HuggingFace on first use.
+
+### Changes
+
+- LLM: structured query expansion via JSON schema grammar constraints.
+  Model produces typed expansions — **lexical** (BM25 keywords), **vector**
+  (semantic rephrasings), **HyDE** (hypothetical document excerpts) — so each
+  routes to the right backend instead of sending everything everywhere.
+- LLM: lazy model loading with 2-minute inactivity auto-unload. Keeps memory
+  low when idle while avoiding ~3s model load on every query.
+- Search: conditional query expansion — when BM25 returns strong results, the
+  expensive LLM expansion is skipped entirely.
+- Search: multi-chunk reranking — documents with multiple relevant chunks
+  scored by aggregating across all chunks rather than best single chunk.
+- Search: cosine distance for vector search (was L2).
+- Search: embeddinggemma nomic-style prompt formatting.
+- Testing: evaluation harness with synthetic test documents and Hit@K metrics
+  for BM25, vector, and hybrid RRF.
+
+## [0.5.0] - 2025-12-13
+
+Collections and contexts moved from SQLite tables to YAML at
+`~/.config/qmd/index.yml`. SQLite was overkill for config — you can't share
+it, and it's opaque. YAML is human-readable and version-controllable. The
+migration was extensive (35+ commits) because every part of the system that
+touched collections or contexts had to be updated.
+
+### Changes
+
+- Config: YAML-based collections and contexts replace SQLite tables.
+  `collections` and `path_contexts` tables dropped from schema. Collections
+  support an optional `update:` command (e.g., `git pull`) before re-index.
+- CLI: `qmd collection add/list/remove/rename` commands with `--name` and
+  `--mask` glob pattern support.
+- CLI: `qmd ls` virtual file tree — list collections, files in a collection,
+  or files under a path prefix.
+- CLI: `qmd context add/list/check/rm` with hierarchical context inheritance.
+  A query to `qmd://notes/2024/jan/` inherits context from `notes/`,
+  `notes/2024/`, and `notes/2024/jan/`.
+- CLI: `qmd context add / "text"` for global context across all collections.
+- CLI: `qmd context check` audit command to find paths without context.
+- Paths: `qmd://` virtual URI scheme for portable document references.
+  `qmd://notes/ideas.md` works regardless of where the collection lives on
+  disk. Works in `get`, `multi-get`, `ls`, and context commands.
+- CLI: document IDs (docid) — first 6 chars of content hash for stable
+  references. Shown as `#abc123` in search results, usable with `get` and
+  `multi-get`.
+- CLI: `--line-numbers` flag for get command output.
+
+## [0.4.0] - 2025-12-10
+
+MCP server for AI agent integration. Without it, agents had to shell out to
+`qmd search` and parse CLI output. The monolithic `qmd.ts` (1840 lines) was
+split into focused modules with the project's first test suite (215 tests).
+
+### Changes
+
+- MCP: stdio server with tools for search, vector search, hybrid query,
+  document retrieval, and status. Runs over stdio transport for Claude
+  Desktop and MCP clients.
+- MCP: spec-compliant with June 2025 MCP specification — removed non-spec
+  `mimeType`, added `isError: true` to errors, `structuredContent` for
+  machine-readable results, proper URI encoding.
+- MCP: simplified tool naming (`qmd_search` → `search`) since MCP already
+  namespaces by server.
+- Architecture: extract `store.ts` (1221 LOC), `llm.ts` (539 LOC),
+  `formatter.ts` (359 LOC), `mcp.ts` (503 LOC) from monolithic `qmd.ts`.
+- Testing: 215 tests (store: 96, llm: 60, mcp: 59) with mocked Ollama for
+  fast, deterministic runs. Before this: zero tests.
+
+## [0.3.0] - 2025-12-08
+
+Document chunking for vector search. A 5000-word document about many topics
+gets a single embedding that averages everything together, matching poorly for
+specific queries. Chunking produces one embedding per ~900-token section with
+focused semantic signal.
+
+### Changes
+
+- Search: markdown-aware chunking — prefers heading boundaries, then paragraph
+  breaks, then sentence boundaries. 15% overlap between chunks ensures
+  cross-boundary queries still match.
+- Search: multi-chunk scoring bonus (+0.02 per additional chunk, capped at
+  +0.1 for 5+ chunks). Documents relevant in multiple sections rank higher.
+- CLI: display paths show collection-relative paths and extracted titles
+  (from H1 headings or YAML frontmatter) instead of raw filesystem paths.
+- CLI: `--all` flag returns all matches (use with `--min-score` to filter).
+- CLI: byte-based progress bar with ETA for `embed` command.
+- CLI: human-readable time formatting ("15m 4s" instead of "904.2s").
+- CLI: documents >64KB truncated with warning during embedding.
+
+## [0.2.0] - 2025-12-08
+
+### Changes
+
+- CLI: `--json`, `--csv`, `--files`, `--md`, `--xml` output format flags.
+  `--json` for programmatic access, `--files` for piping, `--md`/`--xml` for
+  LLM consumption, `--csv` for spreadsheets.
+- CLI: `qmd status` shows index health — document count, size, embedding
+  coverage, time since last update.
+- Search: weighted RRF — original query gets 2x weight relative to expanded
+  queries since the user's actual words are a more reliable signal.
+
+## [0.1.0] - 2025-12-07
+
+Initial implementation. Built in a single day for searching personal markdown
+notes, journals, and meeting transcripts.
+
+### Changes
+
+- Search: SQLite FTS5 with BM25 ranking. Chose SQLite over Elasticsearch
+  because QMD is a personal tool — single binary, no server dependencies.
+- Search: sqlite-vec for vector similarity. Same rationale: in-process, no
+  external vector database.
+- Search: Reciprocal Rank Fusion to combine BM25 and vector results. RRF is
+  parameter-free and handles missing signals gracefully.
+- LLM: Ollama for embeddings, reranking, and query expansion. Later replaced
+  with node-llama-cpp in 0.6.0.
+- CLI: `qmd add`, `qmd embed`, `qmd search`, `qmd vsearch`, `qmd query`,
+  `qmd get`. ~1800 lines of TypeScript in a single `qmd.ts` file.

+name: release
+description: Manage releases for this project. Validates changelog, installs git hooks, and cuts releases. Use when user says "/release", "release 1.0.5", "cut a release", or asks about the release process. NOT auto-invoked by the model.
+disable-model-invocation: true
+---
+
+# Release
+
+Cut a release, validate the changelog, and ensure git hooks are installed.
+
+## Usage
+
+`/release 1.0.5` or `/release patch` (bumps patch from current version).
+
+## Process
+
+When the user triggers `/release <version>`:
+
+1. **Install hooks** — run `scripts/install-hooks.sh` (idempotent)
+2. **Validate changelog** — confirm `## [Unreleased]` has content
+3. **Preview** — show the user what will be released (unreleased content + minor series rollup via `scripts/extract-changelog.sh`)
+4. **Ask for confirmation** — do NOT proceed without explicit user approval
+5. **Run `scripts/release.sh <version>`** — renames `[Unreleased]`, bumps version, commits, tags
+6. **Remind** — tell the user to `git push origin main --tags`
+
+If any step fails, stop and explain. Never force-push or skip validation.
+
+## Changelog Standard
+
+The changelog lives in `CHANGELOG.md` and follows [Keep a Changelog](https://keepachangelog.com/) conventions.
+
+### Heading format
+
+- `## [Unreleased]` — accumulates entries between releases
+- `## [X.Y.Z] - YYYY-MM-DD` — released versions
+
+The release script renames `[Unreleased]` → `[X.Y.Z] - date` and inserts a
+fresh empty `[Unreleased]` section automatically.
+
+### Structure of a release entry
+
+Each version entry has two parts:
+
+**1. Highlights (optional, 1-4 sentences of prose)**
+
+Immediately after the version heading, before any `###` section. This is the
+elevator pitch — what would you tell someone in 30 seconds? Only include for
+releases with significant changes. Skip for small patches.
+
+```markdown
+## [1.1.0] - 2026-03-01
+
+QMD now runs on both Node.js and Bun, with up to 2.7x faster reranking
+through parallel contexts. GPU auto-detection replaces the unreliable
+`gpu: "auto"` with explicit CUDA/Metal/Vulkan probing.
+```
+
+**2. Detailed changelog (`### Changes` and `### Fixes`)**
+
+```markdown
+### Changes
+
+- Runtime: support Node.js (>=22) alongside Bun. The `qmd` wrapper
+  auto-detects a suitable install via PATH. #149 (thanks @igrigorik)
+- Performance: parallel embedding & reranking — up to 2.7x faster on
+  multi-core machines.
+
+### Fixes
+
+- Prevent VRAM waste from duplicate context creation during concurrent
+  `embedBatch` calls. #152 (thanks @jkrems)
+```
+
+### Writing guidelines
+
+- **Explain the why, not just the what.** The changelog is for users.
+- **Include numbers.** "2.7x faster", "17x less memory".
+- **Group by theme, not by file.** "Performance" not "Changes to llm.ts".
+- **Don't list every commit.** Aggregate related changes.
+- **Credit contributors:** end bullets with `#NNN (thanks @username)` for
+  external PRs. No need to credit the repo owner.
+
+### What not to include
+
+- Internal refactors with no user-visible effect
+- Dependency bumps (unless fixing a user-facing bug)
+- CI/tooling changes (unless affecting the release artifact)
+- Test additions (unless validating a fix worth mentioning)
+
+## GitHub Release Notes
+
+Each GitHub release includes the full changelog for the **minor series** back
+to x.x.0. Releasing v1.2.3 includes entries for 1.2.3, 1.2.2, 1.2.1, and
+1.2.0. The `scripts/extract-changelog.sh` script handles this, and the
+publish workflow (`publish.yml`) calls it to populate the GitHub release.
+
+## Git Hooks
+
+The pre-push hook (`scripts/pre-push`) blocks `v*` tag pushes unless:
+
+1. `package.json` version matches the tag
+2. `CHANGELOG.md` has a `## [X.Y.Z] - date` entry for the version
+3. CI passed on GitHub for the tagged commit
+
+Run `skills/release/scripts/install-hooks.sh` to install (also runs
+automatically via `bun install` prepare script).
+
+## Scripts
+
+- [`scripts/install-hooks.sh`](scripts/install-hooks.sh) — install/update git hooks
+- Project scripts used during release:
+  - `scripts/release.sh` — rename [Unreleased], bump version, commit, tag
+  - `scripts/extract-changelog.sh` — extract minor series notes for GitHub release
+  - `scripts/pre-push` — pre-push validation hook
