Labelmap restore currently creates temporary scene datasets to access decoded images, then removes them.
Allow decoding to return image data, provenance, and metadata without registering scene content. Keep resource ownership and segmentation attachment explicit.
Account for DICOM assembly, progressive loading, shared inputs, cancellation, cleanup, and parent-image deletion during loading.
