Regression tests added (red first, both hit the exact bad-free): test_core_events.c test_queue_update_replaces_existing_interned_resreq, test_job_update.c test_update_existing_queue_replaces_interned_resreq (the existing queue-update test had deliberately skipped the resreq branch).

Also: round 6 'scheduler restart did not confirm join within 20s (bug-1760 workaround)'. Candidates: dispatch/RUN not in the surviving committed prefix while the scheduler already applied it, or worker's retained finish never re-delivered to the new primary (cf. bug-1741 fire-and-forget finish notify). Same chaotic soak passed earlier the same day (21 jobs, 6 resync jobs reconciled), so intermittent.",
