Description

Converting setup.cfg to toml and setting up tool.setuptools instead of setup.py, following glue-viz/glue-qt#49.

pre-commit.ci autofix

I am very much clueless why the B905 errors are popping up all of a sudden now, as it has been in the default rules long before, but I'd rather fix all the Ruff failures in #2546.

[dhomeier]

Turns out ZipWithoutExplicitStrict is a Python>=3.10 only thing, but Ruff was not aware of the
python_requires = >=3.10 in setup.cfg even after the minimum version was increased.
Therefore adding the ignore here after all (I suspect most cases should use zip(..., strict=True) really, but that needs further investigation.

Giving some envs for Python 3.14 (at rc2 now) a try here; probably needs scientific-python-nightly-wheels for compatible h5py and shapely versions, so py314 might be best left to the dev jobs for now.

[dhomeier]

As we have just removed pre-3.10 support, I think it makes sense to add some 3.14 envs now, but probably should weed out some more older ones. Currently there are 5 extra CI jobs.

Looks good to me - feel free to weed out some of the older builds if you like, though can also be done in a separate PR.

I've set up Python rc tests as allowed failures now, as sometimes there are no Pandas nightly wheels available for 3.14 (though Pandas 2.3.2 apparently has an installable wheel for it atm).
