- ValueError → TypeError in all three ensure_*_image_for_* decorators (conversion.py): the decorator intercepts non-ndarray/PIL inputs before the wrapped body runs, so the inner raises were unreachable; fixing at the decorator level fixes all annotators at once
- Remove 5 dead isinstance guards from key_points/annotators.py and 4 from utils/image.py (all now covered by the decorator fix)
- Remove dead assert isinstance(scene, Image.Image) from RichLabelAnnotator.annotate (ensure_pil_image_for_class_method guarantees PIL.Image before inner body)
- Add @ensure_cv2_image_for_class_method to VertexLabelAnnotator.annotate for PIL parity (only decorated annotator missing it)
- Rewrite tests to call public API directly (no __wrapped__ bypass); replace with TestAnnotatorInputValidation class (parametrized, IDs, AAA) + parametrized test_image_utils_wrong_type_raises
- Add Raises: TypeError sections to all 6 annotator .annotate() docstrings, 4 image util docstrings, and 3 decorator docstrings
