feat(scheduler): implement capability-based routing and hub v2
Add comprehensive capability routing system to scheduler hub: - Capability-aware worker matching with requirement/offer negotiation - Hub v2 protocol with structured message types and heartbeat management - Worker capability advertisement and dynamic routing decisions - Orphan recovery for disconnected workers with state reconciliation - Template-based job scheduling with capability constraints Add extensive test coverage: - Unit tests for capability routing logic and heartbeat mechanics - Unit tests for orphan recovery scenarios - E2E tests for capability routing across multiple workers - Hub capabilities integration tests - Scheduler fixture helpers for test setup Protocol improvements: - Define structured protocol messages for hub-worker communication - Add capability matching algorithm with scoring - Implement graceful worker disconnection handling
