* feat(#772): adopt stable Codex hook events + commandWindows for Windows parity
Register three new stable Codex hook events (SubagentStart, Stop,
PostToolUse) wired to gsd-context-monitor.js so Codex installs get
the same context-headroom tracking at subagent and session boundaries
that Claude/Qwen already have.
Add commandWindows field to the SessionStart hook entry on Windows so
Codex uses the .cmd shim directly (Git Bash/MSYS cannot POSIX-exec
node.exe). commandWindows is only emitted on win32; POSIX is unchanged.
Refactor reconcileCodexHooksJsonSessionStart into a generic
reconcileCodexHooksJsonEvent so any event name can be reconciled with
the same dedup/preserve-user-entries logic.
Add gsd-context-monitor.js and .cmd to MANAGED_HOOK_COMMAND_BASENAMES
_BY_SURFACE so idempotent re-runs de-duplicate entries correctly.
30 new tests covering: export surface, event registration for each of
the three events, commandWindows parity (POSIX vs win32), idempotency,
uninstall, and user-entry preservation.
Closes#772

* fix(#772): windows path normalization + docs-lint
- Normalize scriptPath backslashes to forward slashes in
ensureCodexHooksJsonEvent and ensureCodexHooksJsonSessionStart so that
isManagedHookCommand can match stored commands against configDir on
Windows CI runners. path.resolve returns backslash paths on Windows,
but when platform is not 'win32' (e.g. platform:'linux' in tests),
projectManagedHookCommand skips normalization — producing a mismatch
that breaks idempotency deduplication (the same hook entry appended
twice on re-register). Forward-slash paths are always valid in both
Node.js and Codex, so the normalization is safe for all platforms.
- Fix changeset pr: 0 → 827 to resolve fail_malformed_fragment.
- Add Codex hook coverage table to docs/how-to/install-on-your-runtime.md
documenting the SubagentStart/Stop/PostToolUse events + commandWindows
Windows-parity field added by this enhancement.
