refactor: remove Go patrol logic from witness manager (gt-kh6q)

Patrol logic is now handled by mol-witness-patrol molecule executed by Claude.
Removed ~985 lines of Go code:
- run(), checkAndProcess(), healthCheck()
- handleStuckPolecat(), getNudgeCount(), recordNudge(), clearNudgeCount()
- processShutdownRequests(), verifyPolecatState()
- autoSpawnForReadyWork(), getActivePolecatCount(), isAlreadySpawned(), spawnPolecat()
- Plus all helper functions

Kept: NewManager(), stateFile(), loadState(), saveState(), Status(), Start(), Stop()
