Two fixes on top of the follow-up pre-task-script work:
1. The void async IIFE inside the interval handler had no catch, so a
throw from the dynamic import or applyPreTaskScripts escaped as an
unhandled rejection — terminating the container. The initial-batch
path is wrapped by processQuery's outer try/catch; the follow-up
path needs its own. Now logs the error and lets the next tick retry.
2. Re-check `done` immediately before query.push. The flag can flip
true while applyPreTaskScripts is awaited (outer stream finishes
during the script execution); without the re-check we'd push into a
closed query. Claimed messages get released by the host's
processing-claim sweep — same recovery posture as the rest of the
poller.
