LinYushen 3137feecdf feat(task): add claim lease mechanism (Phase 2, MUL-2246) (#2660) ...

Add claim_token + claim_expires_at columns to agent_task_queue and three
new SQL queries for the claim lease protocol:

- ClaimAgentTaskWithLease: generates a UUID token and sets a lease expiry
  when claiming a task, so the daemon must prove it received the response
- StartAgentTaskWithClaimToken: validates the token on StartTask, preventing
  stale daemons from starting requeued tasks
- RequeueExpiredClaimLeases: moves dispatched tasks with expired leases back
  to queued for re-claim

This closes the reliability gap where a claim response lost in transit
leaves a task stuck in dispatched until the 60s dispatch timeout fires.
