Merge branch 'main' into feat/language-columns

Resolved conflicts:
- docs/source/_toctree.yml: keep language_and_recipes + tools (PR) and
  video_encoding_parameters (main); drop dataset_subtask, removed by this PR
- src/lerobot/configs/__init__.py: keep both load_recipe (PR) and the
  VideoEncoderConfig exports (main) in __all__
- uv.lock: regenerated via 'uv lock' against the merged pyproject.toml
