feat(projman): add runaway detection and circuit breaker for agents (#236)
Executor self-monitoring:
- 10+ calls without progress → stop and reassess
- Same error 3+ times → circuit breaker, report failure
- 50+ calls → mandatory progress update
- 80+ calls → budget warning, evaluate completion
- 100+ calls → hard stop, save checkpoint
Orchestrator monitoring:
- Detect stuck agents (no progress for X minutes)
- Intervention protocol for runaway agents
- Timeout guidelines by task size (XS: 15min, S: 30min, M: 45min)
- Recovery actions with Status/Failed label
This prevents agents from running indefinitely (400+ tool calls
observed in Sprint 3) and provides clear stopping criteria.
Closes #236
