- Replace raw KEY_F4 check with Input.is_action_just_pressed("free_camera") to
consume the registered project action (matches F3/F12 dev toggle pattern)
- Reset camera.zoom to Vector2.ONE when toggling free camera off so zoom does
not bleed into normal gameplay
- Add free_camera_mode guard to InputMapper._unhandled_input() so discrete
actions (INTERACT, stance, pause) are suppressed alongside movement
- Add client/tests/test_free_camera.gd: flag default, movement suppression,
discrete action suppression, zoom constant contracts
