Runner stuck at `BrokerMigration message received. Polling Broker for messages...`

Describe the bug

Question

Is there anything we can do to get more debug information out of the runners?

Start with the MessageListener log entries around BrokerMigration message received and review the related session, broker, and diagnostic output shown in the report. Determine what prevents the Ubuntu 22.04 runner on version 2.317.0 from receiving jobs, then document the additional debug information or concrete fix needed to restore job polling.
