The mail router was incorrectly routing rig-level addresses
(e.g., gastown/crew/max) to {rig}/.beads instead of town beads.
This caused mail to be invisible when agents checked their inbox.
Two-level beads architecture:
- ALL mail uses town beads ({townRoot}/.beads)
- Rig-level beads are for project issues only
