## Title

    Research note: The uv dependency cache is documented as disposable but useful, and uv cache clean or uv cache clean PACKAGE are documen

## Body

    What I found:
    uv uses aggressive caching to avoid re-downloading and re-building dependencies that have already been fetched or built.
    uv cache clean clears the entire cache; uv cache clean PACKAGE (for example uv cache clean ruff) clears cache entries for one package.
    
    Evidence:
    https://docs.astral.sh/uv/concepts/cache/ · https://docs.astral.sh/uv/reference/storage/
    
    Still unknown:
    Typical long-term cache growth rate on a given machine without periodic measurement.
    
    Useful next check:
    Typical long-term cache growth rate on a given machine without periodic measurement.
