`run_once` returned from `_service_subprocess(1)` as soon as any runner
socket had data, so every log line or request from the runner started another
full pass of claim queries, `clean_unused` and the heartbeat check. Now it
keeps servicing the runner until the second is up, and only cuts the wait short
when trigger events or failures arrive, so those are still handled right away.
With a watcher trigger that logs every 10 ms, a 6 second run on SQLite went
from 92 passes to 6. The new unit tests cover the full-second wait and the
early exit on events.
closes: #77061
