Lifecycle:
- Queue clears and deletes leave a run whose master prompt is currently
executing alone, as ComfyUI leaves the running prompt alone; previously an
executing orchestrator-only head run could be cancelled out from under its
waiting Collector.
- The sweep now also drops worker-assigned runs whose queued delegate prompt
left the queue without the Collector finishing, releasing their result
queues instead of leaking them and polling forever.
- Completed runs release their result queues, and orchestration no longer
pre-creates result queues when load balance picks the master alone.
Transport:
- A websocket timeout during connect, before anything was sent, is a plain
failure the dispatcher may retry elsewhere; only timeouts after the prompt
was sent remain AmbiguousDispatchError.
Efficiency and cleanup:
- One WorkerSnapshot per worker per cycle answers every run's "is my job
there" question (queue first, history only when needed).
- Sweep and cancellation snapshot queued/running prompt ids once per pass.
- probe_worker_queues reuses dispatch._probe_worker_queue; the dead
aggregate idle/busy probe helper is gone.
Rebased on "never replay load-balanced runs on missing history": an
unresolved submission stays on hold until delivery or positive evidence,
so there is no rejection path to fix and no bounded hold.
