the ci error looks odd:

ImportError while loading conftest '/home/runner/work/pandera/pandera/tests/core/conftest.py'.

btw @g-as I just merged https://github.com/unionai-oss/pandera/pull/1916, which does away with the need for maintaining ci and dev requirements files. Also migrate to using uv as preferred package manager for development.

Alright. I'll rebase accordingly. Thanks for the heads-up.
