[Gastown] Beads failing after repeated dispatch attempts - merge queue/refinery issues

[kilo-code-bot]

What happened?

Multiple beads are failing after 5 dispatch attempts across different agents. The pattern shows:

1. Beads get dispatched successfully (status becomes "in_progress")
2. After ~5 dispatch cycles, beads move to "failed" status
3. The gt:pr-fixup label was used but didn't prevent the retry loop
4. Agents get stuck with high dispatch_attempts (40+ in some cases)

This affects critical work like VPN routing fixes and RemoteBlocklistWorker. The agents appear to complete work but the merge/review cycle fails, causing repeated dispatches until max attempts reached. This is causing significant delays in critical bug fixes.
