Companion to CB-109. When a worker disappears mid-turn (pane crash → herdr
*_not_found), the status poller drops the target, which failed only *queued*
messages — a message already DELIVERED is out of the queue, so its send's
rendezvous was left hanging until the 30-min async timeout. Injector.drop now
fires onTurnFailed for a delivered-but-unresolved turn (awaitingCompletion), so
the send resolves as WORKER_FAILED. Reuses the CB-109 resolver path; the failure
reason is neutral to cover both wedge (stuck) and vanish (gone).
