Session names `gt-mayor` and `gt-deacon` were hardcoded, causing tmux
session name collisions when running multiple towns simultaneously.
Changed to `gt-{town}-mayor` and `gt-{town}-deacon` format (e.g.,
`gt-ai-mayor`) to allow concurrent multi-town operation.
Key changes:
- session.MayorSessionName() and DeaconSessionName() now take townName param
- Added workspace.GetTownName() helper to load town name from config
- Updated all callers in cmd/, daemon/, doctor/, mail/, rig/, templates/
- Updated tests with new session name format
- Bead IDs remain unchanged (already scoped by .beads/ directory)

Add Claude Code Stop hook that automatically records session costs when
sessions end. The hook calls `gt costs record` which now can derive the
session name from GT_* environment variables (GT_RIG, GT_POLECAT, GT_CREW,
GT_ROLE).
Changes:
- Add deriveSessionName() to infer tmux session name from environment
- Add Stop hook to settings-autonomous.json and settings-interactive.json
- Add unit tests for deriveSessionName function
When a Gas Town session ends, the Stop hook fires and records the session
cost as a bead event. Costs then appear in `gt costs --today` output.

- Updated `gt costs record` to create session.ended events in beads
- Updated `gt costs --today/--week` queries to use bd instead of JSONL
- Removed JSONL ledger support (getLedgerPath, readLedger, WriteLedgerEntry)
- Session costs now stored with event_kind, actor, target, and payload fields
- Filed bd-xwvo for beads bug where --rig flag loses event fields

Implements cost tracking v1 for Gas Town agents:
- `gt costs` shows live costs scraped from running tmux sessions
- `gt costs --today/--week` shows historical costs from ledger
- `gt costs --by-role/--by-rig` shows cost breakdowns
- `gt costs record` for Stop hook integration to record final costs
Cost ledger stored at ~/.gt/costs.jsonl with JSONL entries per session.
