chore: silence bot reviewers (Claude high-signal, CodeRabbit disabled)

[thomasluizon]

Summary

The chat-clarification PR (#167) generated 14 rounds of bot reviews and 101 resolved threads. Each push produced fresh findings — eventually all just style / wording / hypothetical-future-proofing. The loop never converges because bots are optimized to surface findings, not to approve.

This PR rewrites .github/workflows/claude-review.yml to enforce a strict high-signal-only bar (correctness, security, contract break, missing-test on mutating state, AGENTS.md hard rules) and requires Claude to pick one of three formal review states: APPROVE (default), REQUEST_CHANGES, or COMMENT. Manufacturing nits to avoid approving is explicitly called out as a bug.

CodeRabbit and ChatGPT Codex auto-reviews are disabled at the integration level (their respective dashboards / app uninstalls), not via repo files.

Why now

Real correctness/security findings landed in rounds 1-6 of the chat-clarification review. Rounds 7-14 were all polish: EventId ordering, comment wording, optional-chaining-vs-typeof flip-flops, .nullable().optional() modifier purity. None blocked merging.

Test plan

• Merge this PR
• Push a trivial commit to PR fix: NeedsClarification for habit-flavored titles without frequency #167 — confirm Claude APPROVES (most likely) or posts only correctness/security findings
• Confirm CodeRabbit and Codex stay silent (handled at integration level, not by this PR)

Follow-ups (manual, not in this PR)

• Disable CodeRabbit auto-review at https://app.coderabbit.ai or uninstall the GitHub App at https://github.com/settings/installations
• Disable Codex for these repos at https://chatgpt.com/codex/cloud/settings/general
