Add emergency aftermath: evacuation, investigation, review copy

- Responder outcomes now reach the shift review
  (ShiftCoordinator.responder_outcomes), and the review screen names them.
- "evacuation" (emergency call, low danger, no weapon) actually clears the entrance:
  the door is locked, every NPC flees and is marked as leaving, and a
  security_failure reputation hit applies.
- An emergency call the situation did not justify (no weapon, danger <= 1) appends
  an investigation note, records investigation_opened, and applies the existing
  false_report hit. The review lists the investigations.
- Fix dispatch dying after the first shift: coordinator.setup() builds a new
  RadioSystem, so the responder_arrived connection made in _ready was lost on every
  venue switch/restart. _connect_radio() re-wires it beside _connect_crowd().

Tests/docs
- Headless suite 105 -> 113 (test_emergency_aftermath.gd), new smoke_emergency.gd
  covering the investigation, evacuation aftermath, and review copy.
- README controls/status/smoke checklist, TODO section moved to DONE, MEMORY notes.
- Version 0.2.5.
