review loop

Repeat the following cycle on the current branch's changes against main (max 3 iterations):

1. Review — Spawn 6 reviewer agents in parallel:
   • reviewer-code-quality
   • reviewer-security
   • reviewer-performance
   • reviewer-test-coverage
   • reviewer-conventions
   • reviewer-holistic
2. Triage — Review agent findings and keep only what you also deem noteworthy. Classify each as Fix (clear defects, must fix) or Skip (style, nitpicks, scope creep). Show a brief table before changing anything.
3. Fix only the "Fix" items. Keep changes minimal.
4. Verify with npm run lint and npm run test. Fix any regressions and repeat this step until all checks pass before continuing.
5. Re-review only the newly changed lines. Do not re-raise skipped items.

Stop when no "Fix" items remain or 3 iterations are reached. Print a summary of what was fixed and what was skipped.
