bindings: python: bump ciwheel to 3.1+ for CPython 3.14 wheels

[vfazio]

https://cibuildwheel.pypa.io/en/stable/changelog/#v310

We can get ahead of the curve and generate + test CPython 3.14 wheels. 3.14 RC will remain ABI compatible with the final release, so anything we generate now should work.

libgpiod/bindings/python/generate_pypi_artifacts.sh

Line 111 in cd32f27

${venv_python} -m pip install build==1.2.2.post1 cibuildwheel==2.21.3

Note that we will want to add a condition to skip free-threaded builds as they will be on by default since it is no longer experimental.

See pypa/cibuildwheel#2503

libgpiod/bindings/python/generate_pypi_artifacts.sh

Line 117 in cd32f27

CIBW_BUILD=${CIBW_BUILD:-"cp*"} CIBW_ARCHS=${CIBW_ARCHS:-"x86_64,aarch64"} \

We should be able to specify CIBW_SKIP=${CIBW_SKIP:-"cp31?t-*"} (untested)

I'm slowly working on this. I have something staged in https://github.com/vfazio/libgpiod/tree/vfazio-3.14-wheels

Just posting some evidence using 3.14.0-rc2:

Just a note that 3.14 releases on Oct 7. I'm trying to hurry up with the other changes but chances are I won't get everything in by that date

I think we should hold off on cutting a release and uploading 3.14 wheels until after everything gets merged in.

Maybe it makes sense for me to request a cut of the python bindings via a GL issue when everything looks ok?

Maybe it makes sense for me to request a cut of the python bindings via a GL issue when everything looks ok? Can you rephrase this, I'm not sure what this is about?

And does it mean I should not pick up the patch you send wrt this?

[vfazio]

You can pick up the patch, I would just hold off on cutting the release wheels and generating wheels for the moment until the other patch series is either accepted or rejected. I hope to have it up today
