Two gaps in the next-free-GPU dispatcher:
A run was registered with the dispatcher before the master prompt reached
the ComfyUI queue. Prompt validation yields to the event loop, so a sweep
in that window saw the run as neither queued nor running and dropped it.
Runs are now registered unqueued and ignored by sweep and claim until the
orchestrator marks them queued; a failed queue still discards them.
When a worker had been dispatched but the master's delegate prompt could
not be re-queued, the run's record was removed, leaving nothing to collect
the worker's result. The record now stays assigned to the worker with the
requeue pending, and the dispatcher retries it with backoff until the
delegate prompt is back on the master queue; tracking ends only when the
Collector finishes.
