"""Prepare a Kaggle/Colab session for a uzu lane.

Robustness notes:
- ``hf download --include`` behaviour differs between huggingface_hub versions
  (some accept a single value only). The kit is ~5 MB, so this script downloads
  the whole dataset and avoids ``--include`` entirely.
- The kit is rebuilt from a fixed manifest (``scripts/build_kit.py``), so a
  missing script cannot silently slip in.

Usage:
    python scripts/bootstrap_kaggle.py                 # install deps + fetch kit
    python scripts/bootstrap_kaggle.py --no-install    # kit only
    python scripts/bootstrap_kaggle.py --dry-run
