- main.gd: add has("entity_id") guard to _play_recognition_chimes()
(matches defensive pattern in _play_close_sound_events and update_sound_events)
- sound_indicator_renderer.gd: rename _color_for_type → color_for_type
(public testable API, not an internal-only method)
- test_rendering.gd: update test calls to match rename
