- Add missing _test_input_queue proxy to SimBridge (26 call sites across
6 test files broken by TestHarness extraction)
- Parent quit dialog to SceneTree root instead of caller node to prevent
orphaned reference if caller freed before user responds
- Remove deprecated rng.randomize() call (Godot 4 auto-seeds)
- Clear debug overlay state (_npc_paths, tick timing) on session change
via new GameState.game_id_changed signal to prevent entity ID collisions
- Update settings_dialog quit_to_menu() call site (no-arg signature)
