Add PLAN verbs and fix dead incident recording

Verbs (PLAN levels 1-3)
- Eye contact: own Level 1 radial slice, logged as "eye contact".
- Recognition is a player decision: "Recognize" sets NPCController.player_recognized,
  writes access evidence, and GameManager only then appends a RECOGNITION artifact.
  It is no longer implied by NPC type.
- Body camera: real flag (off by default) driving the REC overlay; B toggles it and
  a formal warning arms it automatically, writing a body_camera incident event.
- Blocking stations the guard 0.9 m from the person toward the entrance and turns
  to face them, instead of only emitting the escalation level.
- Request reason: Level 3 ask answered from the NPC's seeded dialogue_lines.
- Radial grows to 12 slices (174 px outer radius, centered labels).

Incident recording fix
- IncidentRecorder.start_incident() was never called, so add_event /
  add_access_evidence / add_escalation silently no-opped and the shift review
  always reported zero incidents. Incidents now open on focus (guarded by
  has_open_incident), verbs call _ensure_incident, and ShiftCoordinator closes
  leftovers as "unresolved" before building the review.

Copy and docs
- 9 new string keys (eye contact, body camera, recognition, reason, station).
- README controls, 26-step smoke checklist, test count, status lists.
- TODO section moved to DONE; MEMORY records the verb design and the recorder bug.

Verification: headless 98/98, smoke_plan_verbs.gd + smoke_session_shell.gd +
windowed smoke_focus_radial.gd all pass. Version bumped to 0.2.3.
