* feat: add /careful, /freeze, /guard, /unfreeze safety hook skills
Four new on-demand skills using Claude Code's PreToolUse hooks:
- /careful: warns before destructive commands (rm -rf, DROP TABLE, force-push, etc.)
- /freeze: blocks file edits outside a specified directory
- /guard: composes both into one command
- /unfreeze: clears freeze boundary without ending session
Pure bash hook scripts with Python fallback for JSON edge cases.
Safe exceptions for build artifacts (node_modules, dist, .next, etc.).
Hook fire telemetry logs pattern name only (never command content).

* feat: add skill usage telemetry to preamble
TemplateContext system passes skill name through resolver pipeline so
each generated SKILL.md gets its own name baked into the telemetry line.
Appends to ~/.gstack/analytics/skill-usage.jsonl on every invocation.
Covers 14 preamble-using skills + 4 hook skills (inline telemetry).
JSONL format: {"skill":"ship","ts":"...","repo":"my-project"}

* feat: add analytics CLI for skill usage stats
bun run analytics reads ~/.gstack/analytics/skill-usage.jsonl and shows
top skills, per-repo breakdown, hook fire stats, and daily timeline.
Supports --period 7d/30d/all. Handles missing/empty/malformed data.
22 unit tests cover parsing, filtering, formatting, and edge cases.

* feat: add skills-used-this-week to /retro
Retro Step 2 now reads skill-usage.jsonl and shows which gstack skills
were used during the retro window. Follows the same pattern as the
Greptile signal and Backlog Health metrics — read file, filter by date,
aggregate, present. Skips silently if no analytics data exists.

* test: add hook script and telemetry tests
32 unit tests for check-careful.sh covering all 8 destructive patterns,
safe exceptions, Python fallback, and malformed input handling.
7 unit tests for check-freeze.sh covering boundary enforcement,
trailing slash edge case, and missing state file.
Telemetry tests verify per-skill name correctness in generated output.
Adds careful/freeze/guard/unfreeze/document-release to ALL_SKILLS.

* chore: bump version to 0.6.5 + changelog + mark TODOs shipped
Safety hook skills and skill usage telemetry shipped.
Analytics CLI and /retro integration included.

* feat: /debug auto-freezes edits to the module being debugged
Add PreToolUse hooks (Edit/Write) to debug/SKILL.md.tmpl that reference
the existing freeze/bin/check-freeze.sh. After Phase 1 investigation,
/debug locks edits to the narrowest affected directory.
Graceful degradation: if freeze script is unavailable, scope lock is
skipped. Users can run /unfreeze to remove the restriction.
Deferred 6 enhancements to TODOS.md, gated on telemetry showing the
freeze hook actually fires in real debugging sessions.
