Root cause: WorkerService.ClaimTask() was modifying the audit entry
in memory but never persisting it to the database. This caused build
tasks to remain stuck at "pending" status even after being claimed.
Changes:
- Add UpdateStatus method to port.BuildAudit interface
- Implement UpdateStatus in postgres.BuildAuditRepository
- Fix ClaimTask to call audit.UpdateStatus() to persist status
- Add test coverage for audit update during task claim
- Update all mock implementations
