Merge branch 'main' into garrytan/team-supabase-store

Resolved 15 conflicts:
- session-runner.ts: kept both costs array (ours) and model/timing
  telemetry (main), renamed loop var to avoid shadowing model param
- skill-e2e.test.ts: accepted deletion (main split into separate files)
- gen-skill-docs.ts: kept our codex review flow with $PROJECTS_DIR paths
- plan review templates: took main + re-applied $PROJECTS_DIR paths,
  replaced gstack-review-log with inline approach
- TODOS.md: took main's shipped status for E2E model pinning
- Generated SKILL.md + .agents/ files: regenerated from resolved templates
