An async (wait:false) delegation opens a ~55s reverse-rendezvous window when its
worker calls bridge_ask. A lead polling on its normal minutes-long cadence never
sees that window, so the worker times out and proceeds without an answer.
The question is now a third source in the CB-588 per-lead push schedule, with its
own per-item nudge count (CB-598's shape), and it is surfaced by bridge_status and
by REST /sessions/{id}/status and /tasks/{ticket} (which previously dropped turnId
on an ASKING phase, so a REST caller could see the question but not answer it).
