feat(beads): Add hq- prefix helpers for town-level beads (gt-y24km, gt-qgmyz)

Phase 1: Create agent_ids.go with town-level bead ID helpers
- MayorBeadIDTown(), DeaconBeadIDTown(), DogBeadIDTown()
- RoleBeadIDTown() and role-specific helpers (hq-*-role)
- Add deprecation notices to old gt-* prefix functions

Phase 2: Create town-level agent beads during gt install
- initTownAgentBeads() creates hq-mayor, hq-deacon agent beads
- Creates role beads: hq-mayor-role, hq-deacon-role, etc.
- Update rig/manager.go to use rig beads for Witness/Refinery

This aligns with the two-level beads architecture:
- Town beads (~/gt/.beads/): hq-* prefix for Mayor, Deacon, roles
- Rig beads (<rig>/.beads/): <prefix>-* for Witness, Refinery, Polecats
