Add patrol awareness and wiring to gt rig add / gt doctor (gt-7923)

gt rig add changes:
- Seed patrol molecules (Deacon, Witness, Refinery) when adding rig
- Create plugin directories at town (~gt/plugins/) and rig levels
- Update command documentation and structure output

gt doctor changes:
- patrol-molecules-exist: Verify patrol molecules exist
- patrol-hooks-wired: Verify daemon triggers patrols
- patrol-not-stuck: Detect stale wisps (>1h in_progress)
- patrol-plugins-accessible: Verify plugin directories exist
- patrol-roles-have-prompts: Verify role prompts exist

All patrol checks support --fix where applicable.
