Merge branch 'feat/language-columns' into feat/language-annotation-pipeline

Resolve conflicts and pull in the latest PR 1 fixes.

Conflicts:
- pyproject.toml: PR 1 added `lerobot-rollout` and PR 2 added
  `lerobot-annotate` to the same `[project.scripts]` block. Kept both.
- uv.lock: dropped both sides and regenerated against the merged
  `pyproject.toml` (PR 2 dropped the `datatrove` dep when distribution
  moved to HF Jobs; PR 1's lock didn't have it).

Test follow-up:
- `tests/annotations/test_pipeline_recipe_render.py` — PR 1 deleted
  `src/lerobot/configs/recipes/pi05_hirobot.yaml` (review feedback:
  remove the canonical-recipe file; recipes are user-supplied). The
  cross-PR contract this test guards is "the recipe DSL renders
  non-empty messages from pipeline output", which doesn't depend on
  any specific YAML, so the test now builds an inline blend recipe
  with the same coverage. Passes.

Sweep: 82 passed, 2 failed (pre-existing module-impl bugs:
`test_module1_attaches_video_block_to_subtask_prompt`,
`test_module2_mid_episode_emits_paired_interjection_and_speech`).
The PR 1 carryover (`test_emitted_at_raises_on_ambiguous_per_camera_vqa`)
is now passing — the merge brought in PR 1's tightened `_select_one`
ambiguity check.
