docs: add the final-HEAD review gate to CLAUDE.md

[cristim]

Adds a short "## Review gate" section to CLAUDE.md, moved from dotclaude's global pr-lifecycle skill (LeanerCloud/dotclaude#111) and refreshed to the current policy: independent adversarial review on Opus 5.5 (claude-opus-5-5, never Fable); CodeRabbit optional when exact-revision local verification plus a thorough independent review cover the final SHA; green CI; local macOS verification plus Linux CI, no Windows scope; merge only at the reviewed SHA.

Closes #30

• Also rewords the CodeRabbit loop heading and opening so it applies only when CodeRabbit is the chosen review path or the independent-review condition is not met.

The gate also requires merging normally (no --admin, no --no-verify), all actionable findings from any reviewer resolved, the verdict, SHA and evidence recorded on the PR, fixture or mock evidence labeled, and it never authorizes real purchases, deploys or --yes; the CodeRabbit delegation and label-mirror rules no longer assume CR (carried over from dotclaude#114).

Independent review (Opus 5.5) found two gaps (no-bypass rule; an unconditional CR-loop delegation paragraph); both are fixed at this head. Orchestrator verified the final text: the Review gate section is byte-identical across the 4 repos, has no em-dashes, and the only Fable mention says 'never Fable'. Docs-only; pre-commit passed.
