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.

- Create internal/claude package with embedded settings templates
- settings-autonomous.json: gt prime && gt mail check --inject (SessionStart)
- settings-interactive.json: gt prime only (SessionStart)
- Update witness.go: EnsureSettings before session, remove broken gt prime injection
- Update refinery/manager.go: EnsureSettings before session, remove broken NudgeSession
- Update session/manager.go: EnsureSettings for polecats, remove broken issue injection
All autonomous roles (polecat, witness, refinery) now get proper SessionStart hooks
automatically when their sessions are created. No more timing-based gt prime injection.
