Extend worker capabilities with new execution plugins and security features:
- Jupyter plugin for notebook-based ML experiments
- vLLM plugin for LLM inference workloads
- Cross-platform process isolation (Unix/Windows)
- Network policy enforcement with platform-specific implementations
- Service manager integration for lifecycle management
- Scheduler backend integration for queue coordination
Update lifecycle management:
- Enhanced runloop with state transitions
- Service manager integration for plugin coordination
- Improved state persistence and recovery
Add test coverage:
- Unit tests for Jupyter and vLLM plugins
- Updated worker execution tests
Created lifecycle package with foundational types for future extraction:
1. internal/worker/lifecycle/runloop.go (117 lines)
- TaskExecutor interface for task execution contract
- RunLoopConfig for run loop configuration
- RunLoop type with core orchestration logic
- MetricsRecorder and Logger interfaces for dependencies
- Start(), Stop() methods for loop control
- executeTask() method for task lifecycle management
2. internal/worker/lifecycle/health.go (52 lines)
- HealthMonitor type for health tracking
- RecordHeartbeat(), IsHealthy(), MarkUnhealthy() methods
- Heartbeater interface for heartbeat operations
- HeartbeatLoop() function for background heartbeats
Note: These are interface/type foundations for Phase 5.
The actual Worker struct methods remain in runloop.go until
Phase 5 when they'll migrate to use these abstractions.
