- Import sweepStaleReviews, resolveApprovalDecision, dispatchAgentMessage
- Insert stale review sweep into per-company heartbeat loop after budget reset
- Sweep runs on every 15-second heartbeat cycle for each active company
- Local callback stubs for handleTaskStatusChange and handleApprovalResolved
- Error handling prevents sweep failures from crashing the heartbeat loop
- Fix test type casts to use as-unknown-as for vi.fn mock compatibility
- TypeScript compiles cleanly, 249/249 tests pass
