This PR removes pandas and pyarrow from the development dependencies list in
pyproject.tomland runsuv sync.Looks like they can now be safely removed without stopping any content in the code/tests/docs from running. If so, it would make sense to not keep them there - we should be a pure polars shop for the backend and a narwhals shop for the frontend.
Hopefully I'm not missing or breaking anything important.
