The file rename landed in 215ecd6 but the importer updates in
model/__init__.py, model/cxr_vlm.py, evaluation/{evaluate,inference}.py
and training/train.py were left uncommitted, so a clean checkout of HEAD
raised ImportError (from .image_encoder import …, file no longer exists).
Commit only those import-line fixes (6 lines) to make HEAD importable.
