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.

gt prime now internally runs:
- bd prime (beads workflow context)
- gt mail check --inject (mail injection)
This allows a single SessionStart hook to provide complete agent context.
Also added PreCompact and UserPromptSubmit hooks to settings.json.
