fix add long-run watchdog and exportable debug log dump Add alarms-based self-healing for long-running apply drift and expose a user-triggered debug log export so support can collect worker health storage state DNR snapshots and recent logs in a single file Also temporarily comment out CI e2e container commands while race diagnostics are in progress
