feat: Update agent bead lookups to use correct tier (gt-eqptl)

Implement two-level beads architecture for agent lookups:

- Town-level agents (Mayor, Deacon) now use hq- prefix and are
  looked up in town beads (~/.beads/)
- Rig-level agents continue using rig prefix (e.g., gt-) and are
  looked up in rig beads

Changes:
- Add MayorBeadIDTown(), DeaconBeadIDTown(), DogBeadIDTown() helpers
- Add GetTownBeadsPath() for town beads path resolution
- Update gt status to pre-fetch town-level agent beads
- Update agentIDToBeadID() to use town-level IDs
- Update agent_beads_check.go to check/fix in correct tier
- Update agentAddressToIDs() in deacon.go
