feat(formula): update mol-town-shutdown to v3 with full cleanup (gt-ux23f)

Added steps from discovered cleanup operations:
- clear-hooks: Detach all hooked work from agents
- reset-in-progress: Reset in-progress beads to open status
- burn-wisps: Clean up wisp directories and ephemeral beads
- validate-clean: Verify all cleanup operations succeeded

Updated existing steps with more detailed procedures.

Key principles preserved:
- No forcing, no lost work
- Idempotent (safe to run multiple times)
- Crew workers NOT affected (user-managed)
