Ticket #71 PR #22 Review: pass_audit approved
Documentation change to agents/reviewer.md approved:
- Updated to use `gh pr comment` instead of `gh pr review --approve`
- Added two-step review process (GitHub PR comment + Tinker ticket comment)
- Added `gh pr review --approve` to ABSOLUTELY FORBIDDEN
- Updated transition events (pass_audit/fail_audit)
Note: PR includes same scope creep files as previous PRs (#20, #21) - this is a process issue to address separately. The actual ticket work (reviewer.md documentation) is correct.
