* fix: gracefully handle unsupported thread/name/set on older Codex CLI
Codex CLI v0.118.0 does not recognize the thread/name/set JSON-RPC method,
causing startThread() to throw. Thread naming is cosmetic (for job log
labels) and should not block thread creation. Wraps the call in try/catch
so it fails silently on older CLI versions.
Fixes#119
* refactor: only suppress unsupported-method errors for thread/name/set
Address Codex review feedback: the bare catch swallowed all errors
including auth, network, and server failures. Now only suppresses
errors containing 'unknown variant' or 'unknown method' (the specific
error older CLI versions return) and rethrows everything else.
`SpawnedCodexAppServerClient.initialize()` passes `this.options.env` to
`spawn()`, but no caller ever sets `env` in options. In Node.js, passing
`undefined` for `env` gives the child process **no** environment variables,
breaking any model provider that relies on env vars (e.g. DATABRICKS_TOKEN).
Fall back to `process.env` when `this.options.env` is not set, matching the
existing pattern in `broker-lifecycle.mjs` and `codex-companion.mjs`.

* fix: add shell and windowsHide options for Windows spawn in app-server
On Windows, spawn("codex", ["app-server"]) fails with ENOENT because
Node.js cannot resolve .cmd shims without shell: true. This adds
platform-gated shell and windowsHide options to the app-server spawn
call, and uses terminateProcessTree for proper process tree cleanup
since shell: true wraps the child in cmd.exe.
Without terminateProcessTree, plain SIGTERM only kills cmd.exe and
leaves the actual codex node process orphaned — verified with 274+
zombie node.exe processes accumulating on Windows.

* fix: guard terminateProcessTree against PID reuse after process exit
ChildProcess.killed only reflects whether .kill() was called by this
process — it stays false when the child exits on its own. On Windows,
where PIDs are recycled quickly, the 50 ms timer could fire after
cmd.exe has exited and its PID has been reassigned, causing taskkill
to terminate an unrelated process.
Add an exitCode === null check so the tree-kill path is skipped once
the child has already exited.

On Windows, Node.js `spawnSync` without `shell: true` uses
`CreateProcess`, which only resolves `.exe` files. npm installs global
tools (like `codex`) as `.cmd` shims, so `spawnSync("codex", ...)`
returns ENOENT even when codex is correctly installed and on PATH.
Adding `shell: process.platform === "win32"` routes through `cmd.exe`
on Windows, which properly resolves `.cmd`, `.bat`, and PATHEXT entries.
No behavior change on macOS/Linux since the condition evaluates to false.
