Update get and multi-get commands for virtual paths

- Update getDocument() to support qmd:// virtual paths and filesystem paths
- Update multiGet() to handle virtual paths in patterns and comma-separated lists
- Update matchFilesByGlob() in store.ts to return virtual paths
- Remove duplicate getContextForFile() function from qmd.ts
- Use collection-scoped getContextForPath() instead of legacy function
- All get and multi-get tests now passing

Closes qmd-vro

+# Beads - AI-Native Issue Tracking
+
+Welcome to Beads! This repository uses **Beads** for issue tracking - a modern, AI-native tool designed to live directly in your codebase alongside your code.
+
+## What is Beads?
+
+Beads is issue tracking that lives in your repo, making it perfect for AI coding agents and developers who want their issues close to their code. No web UI required - everything works through the CLI and integrates seamlessly with git.
+
+**Learn more:** [github.com/steveyegge/beads](https://github.com/steveyegge/beads)
+
+## Quick Start
+
+### Essential Commands
+
+```bash
+# Create new issues
+bd create "Add user authentication"
+
+# View all issues
+bd list
+
+# View issue details
+bd show <issue-id>
+
+# Update issue status
+bd update <issue-id> --status in_progress
+bd update <issue-id> --status done
+
+# Sync with git remote
+bd sync
+```
+
+### Working with Issues
+
+Issues in Beads are:
+- **Git-native**: Stored in `.beads/issues.jsonl` and synced like code
+- **AI-friendly**: CLI-first design works perfectly with AI coding agents
+- **Branch-aware**: Issues can follow your branch workflow
+- **Always in sync**: Auto-syncs with your commits
+
+## Why Beads?
+
+✨ **AI-Native Design**
+- Built specifically for AI-assisted development workflows
+- CLI-first interface works seamlessly with AI coding agents
+- No context switching to web UIs
+
+🚀 **Developer Focused**
+- Issues live in your repo, right next to your code
+- Works offline, syncs when you push
+- Fast, lightweight, and stays out of your way
+
+🔧 **Git Integration**
+- Automatic sync with git commits
+- Branch-aware issue tracking
+- Intelligent JSONL merge resolution
+
+## Get Started with Beads
+
+Try Beads in your own projects:
+
+```bash
+# Install Beads
+curl -sSL https://raw.githubusercontent.com/steveyegge/beads/main/scripts/install.sh | bash
+
+# Initialize in your repo
+bd init
+
+# Create your first issue
+bd create "Try out Beads"
+```

+# Beads Configuration File
+# This file configures default behavior for all bd commands in this repository
+# All settings can also be set via environment variables (BD_* prefix)
+# or overridden with command-line flags
+
+# Issue prefix for this repository (used by bd init)
+# If not set, bd init will auto-detect from directory name
+# Example: issue-prefix: "myproject" creates issues like "myproject-1", "myproject-2", etc.
+# issue-prefix: ""
+
+# Use no-db mode: load from JSONL, no SQLite, write back after each command
+# When true, bd will use .beads/issues.jsonl as the source of truth
+# instead of SQLite database
+# no-db: false
+
+# Disable daemon for RPC communication (forces direct database access)
+# no-daemon: false
+
+# Disable auto-flush of database to JSONL after mutations
+# no-auto-flush: false
+
+# Disable auto-import from JSONL when it's newer than database
+# no-auto-import: false
+
+# Enable JSON output by default
+# json: false
+
+# Default actor for audit trails (overridden by BD_ACTOR or --actor)
+# actor: ""
+
+# Path to database (overridden by BEADS_DB or --db)
+# db: ""
+
+# Auto-start daemon if not running (can also use BEADS_AUTO_START_DAEMON)
+# auto-start-daemon: true
+
+# Debounce interval for auto-flush (can also use BEADS_FLUSH_DEBOUNCE)
+# flush-debounce: "5s"
+
+# Git branch for beads commits (bd sync will commit to this branch)
+# IMPORTANT: Set this for team projects so all clones use the same sync branch.
+# This setting persists across clones (unlike database config which is gitignored).
+# Can also use BEADS_SYNC_BRANCH env var for local override.
+# If not set, bd sync will require you to run 'bd config set sync.branch <branch>'.
+# sync-branch: "beads-sync"
+
+# Multi-repo configuration (experimental - bd-307)
+# Allows hydrating from multiple repositories and routing writes to the correct JSONL
+# repos:
+#   primary: "."  # Primary repo (where this database lives)
+#   additional:   # Additional repos to hydrate from (read-only)
+#     - ~/beads-planning  # Personal planning repo
+#     - ~/work-planning   # Work planning repo
+
+# Integration settings (access with 'bd config get/set')
+# These are stored in the database, not in this file:
+# - jira.url
+# - jira.project
+# - linear.url
+# - linear.api-key
+# - github.org
+# - github.repo

 # QMD - Quick Markdown Search
 
+**Note**: This project uses [bd (beads)](https://github.com/steveyegge/beads) for issue tracking. Use `bd` commands instead of markdown TODOs. See AGENTS.md for workflow details.
+
 Use Bun instead of Node.js (`bun` not `node`, `bun install` not `npm install`).
 
 ## Commands
 
 ```sh
-qmd add .              # Index markdown files in current directory
+qmd add .                      # Index markdown files in current directory
-qmd status             # Show index status and collections
+qmd context add [path] "text"  # Add context for path (defaults to current dir)
-qmd update-all         # Re-index all collections
+qmd context list               # List all contexts
-qmd embed              # Generate vector embeddings (requires Ollama)
+qmd context rm <path>          # Remove context
-qmd search <query>     # BM25 full-text search
+qmd status                     # Show index status and collections
-qmd vsearch <query>    # Vector similarity search
+qmd update                     # Re-index all collections
-qmd query <query>      # Hybrid search with reranking (best quality)
+qmd embed                      # Generate vector embeddings (requires Ollama)
-qmd get <file>         # Get document content (fuzzy matches if not found)
+qmd search <query>             # BM25 full-text search
-qmd multi-get <pattern> # Get multiple docs by glob or comma-separated list
+qmd vsearch <query>            # Vector similarity search
+qmd query <query>              # Hybrid search with reranking (best quality)
+qmd get <file>                 # Get document content (fuzzy matches if not found)
+qmd multi-get <pattern>        # Get multiple docs by glob or comma-separated list
+```
+
+## Context Management
+
+```sh
+# Add context to current directory (auto-detects collection)
+qmd context add "Description of these files"
+
+# Add context to a specific path
+qmd context add /subfolder "Description for subfolder"
+
+# Add global context to all collections (system message)
+qmd context add / "Always include this context"
+
+# Add context using virtual paths
+qmd context add qmd://journals/2024 "Journal entries from 2024"
+
+# List all contexts
+qmd context list
+
+# Remove context
+qmd context rm qmd://journals/2024
+qmd context rm /  # Remove global context
 ```
