Jiang Bohan dc127f1da4 feat(daemon): Redis empty-claim fast path for /tasks/claim polling ...

Daemons poll /tasks/claim every 30s per runtime; the steady-state
warm-empty case currently runs ListPendingTasksByRuntime against
Postgres on every poll. This collapses that path:

- New ListQueuedClaimCandidatesByRuntime query restricts to status =
  'queued' (the old query also returned 'dispatched' rows that can
  never be reclaimed) and is backed by a partial index keyed on
  (runtime_id, priority DESC, created_at ASC).
- New EmptyClaimCache caches the negative verdict in Redis with a
  30s TTL. ClaimTaskForRuntime checks the cache before SELECT and
  populates it on confirmed-empty results.
- notifyTaskAvailable now invalidates the runtime's empty key before
  kicking the daemon WS, so newly enqueued tasks become claimable
  immediately rather than waiting out the TTL.
- AutopilotService.dispatchRunOnly now goes through
  TaskService.NotifyTaskEnqueued so run_only tasks get the same
  invalidate-then-wakeup contract as every other enqueue path.
