fix(hook): make cross-level hooks visible to mayor/deacon

The gt hook command wasn't finding hooked beads for town-level roles
(mayor, deacon) because of an identity format mismatch:

- When hooking a bead, resolveSelfTarget() sets assignee with trailing
  slash (e.g., "mayor/")
- When querying, buildAgentIdentity() returned without slash ("mayor")

This caused the assignee filter to miss the hooked bead since bd does
exact matching on the assignee field.

Fix:
- Update buildAgentIdentity() to return "mayor/" and "deacon/" with
  trailing slash, matching the format used when setting assignee
- Update isTownLevelRole() to accept both formats for compatibility

Fixes: gt-g6ng2
