Complete Phase 2: Safety Framework Implementation
- Implement DatabaseWatchdog with 20-minute timeout detection and failsafe mode - Add EmergencyStopManager with system-wide and targeted emergency stop functionality - Create AlertManager with multi-channel alert delivery (email, SMS, webhook, SCADA) - Integrate emergency stop checking into SafetyLimitEnforcer (highest priority) - Add comprehensive unit tests for all new safety components - All 95 unit tests passing (100% success rate) Co-authored-by: openhands <openhands@all-hands.dev>
