Mark the polish track as completed:
- status: active -> completed
- current_phase: 0 -> complete
- last_updated: 2026-06-22 -> 2026-06-24
- All 5 phases: pending -> completed
- All 12 tasks: pending -> completed with commit SHAs
- All 10 verification criteria: false -> true
The 10th VC (vc10_pre_existing_violations_unchanged) is true because
the 4 pre-existing exception-handling violations and 7 pre-existing
Optional[T] violations are unchanged from baseline (documented as NG1
and NG2 in metadata.json::known_issues and explicitly out of scope).
