[Gastown] Refinery agent stuck idle despite being hooked to in_review bead (dispatch not firing)

What happened?

Town 0f3ae5da-db5f-49a8-b508-7ab409975608, rig 933bc849-eff1-4574-9955-34be2b5e22f6 (fila-palette). Convoy a68a9577-99aa-4df9-b1ee-477170154d2a ("Fix all open GitHub issues #308-#323") has 3 beads stuck in_review (#309, #312, #313) for ~3 hours. All agents are idle.

Repro steps:

1. Convoy had 3 beads move to in_review status around 01:17-01:34.
2. The refinery agent (39c3ed8e-5020-419c-9ef0-093739e3f1fd) went idle at 01:19 and never picked up the queued reviews — it had no current_hook_bead_id.
3. gt_agent_reset was called on the refinery — it reset to idle but still no hook, still no dispatch.
4. gt_bead_reassign of bead [Gastown] PR 6: tRPC Routes — Town & Rig Management #309 (9f18fe16-71c0-4edb-ad10-93c739d7ce36) to the refinery succeeded — current_hook_bead_id is now set to the bead. But the agent remains status=idle, dispatch_attempts=0.
5. gt_nudge in both wait-idle and immediate modes queued successfully but the agent never transitioned to in_progress or began dispatching.

Expected: Once an agent is hooked to a ready bead, the dispatch alarm should fire and the agent should transition to in_progress.
Actual: The refinery is hooked (current_hook_bead_id set) but the dispatch never fires — dispatch_attempts stays 0, status stays idle. Nudges, reset, and reassign all fail to start it.

This blocks the entire convoy: downstream beads #318, #319, #323, #314 are all dependency-blocked on these in_review beads and cannot dispatch until they close.

Tried: gt_agent_reset, gt_bead_reassign, gt_nudge (immediate + wait-idle). None caused the agent to dispatch.
