Publish terminal daemon completions to the session that started the
process so idle agents can resume without polling hub status.
Persist every unacknowledged generation with a stable completion ID and
immutable snapshot. Replay the collection after reconnect or broker
recovery, and clear each event only after the owning client acknowledges
it.

- Stamped a per-owner delivery generation on each async-result follow-up.
- Bumped the generation on session transitions and dropped stale-generation
deliveries at format-time and flush-time, closing the job-id-reuse race.
- Reverted the fragile persistent-suppression eviction to full row removal.
- Covered the reused-id late-delivery contract at the transcript level.
Fixes#6828
- Evicted jobs now drop queued/in-flight deliveries and stay suppressed.
- /new clears already-queued async-result yield follow-ups.
- Added a transcript-level test asserting no prior-session result leaks.
Fixes#6828
A completed delivery hands off from the AsyncJobManager to the session's
yield queue before the follow-up is injected (idle flush runs on a delayed
post-prompt task; mid-turn entries wait for the next step boundary). In
that window hasPendingAsyncWork() read false from manager state alone, so
a terminal yield observed there terminated the run and silently dropped
the delivered result - the stale-success class the quiescence barrier
exists to prevent. The wake predicate now also counts queued async-result
entries on the yield queue; added a session-level contract test that
pinned the window (failed before, passes after).
Three-piece architecture so subagents inherit async.enabled and
bash.autoBackground.enabled instead of having both force-disabled:
- Owner-routed delivery: AsyncJobManager gains registerDeliverySink /
waitForOwnerJobs; every AgentSession registers a sink for its own agent
id, so background job results inject into the owning agent's run.
Owned deliveries with no live sink dead-letter (result retained on the
job row) instead of misrouting into the first top-level session.
- Quiescence barrier: a subagent's final yield with owner jobs still
running/undelivered is a scheduling pause, not completion. The run
driver notifies the model once (hub wait/cancel), settles owner work,
and folds results in as async-result follow-ups; teardown cancels and
awaits surviving jobs before isolation worktree capture/cleanup.
- Steering soft channel: queued steering no longer hard-aborts
non-interruptible tools; it aborts interruptible waits and raises a
cooperative ToolCallContext.steeringSignal. The mid-batch watch runs
for every batch, and auto-backgroundable bash backgrounds itself on
steer so incoming messages inject promptly with no work lost.
