summary

• Live.cache() dereferenced self._dvc_repo without checking it, but get_dvc_repo() returns None outside a git repo. Live(cache_images=True) + log_image() + end() in a plain directory (colab, kaggle, any non-git cwd) raised AttributeError: 'NoneType' object has no attribute 'add' from end(), which catch_and_warn(DvcException) does not catch.
• cache() now warns and returns when there is no dvc repo, the same way log_artifact() already does. integrations that pass cache_images=True no longer fail at the end of training outside git.

measured

Live(cache_images=True) + log_image() + end()	before	after
cwd outside git	AttributeError from end()	warning, image kept on disk, no images.dvc
git + dvc init (test_cache_images[True])	images.dvc written	unchanged

full suite: 255 passed; the 2 test_huggingface_log_model[DVCLiveCallback1-*-True] failures (Trainer.__init__() got an unexpected keyword argument 'tokenizer') also fail on main.

• ❗ I have followed the Contributing to DVCLive guide.
• 📖 No documentation update needed.
