- Implement WispGCCheck in internal/doctor/wisp_check.go
- Scans rigs for wisps older than 1 hour threshold
- Fix runs `bd --no-daemon wisp gc` in each affected rig
- Register wisp-gc check in gt doctor
- Update help text to document cleanup checks
- Simplify Deacon patrol session-gc step to just use gt doctor --fix
Now `gt doctor --fix` handles all cleanup:
- orphan-sessions: Kill orphaned tmux sessions
- orphan-processes: Kill orphaned Claude processes
- wisp-gc: Garbage collect abandoned wisps (>1h)
