Extend Python version support to 3.13 and 3.14

[Copilot]

Extend Python version checks to 3.14

• Analyze current Python version configuration across the repository
• Update CI workflow (.github/workflows/ci.yml) to add Python 3.13 and 3.14
• Update build-wheels workflow (.github/workflows/build-wheels.yml) to add Python 3.13 and 3.14
• Update pyproject.toml cibuildwheel configuration to include cp313 and cp314
• Verify changes don't break existing configuration (YAML and TOML syntax validated)
• Update README.md Python version badge to include 3.13 and 3.14
• Update BuildingWheels.md documentation to reflect 3.13 and 3.14 support
• Address code review feedback (fixed ABI tag documentation)
• Fix CI failure: Upgraded cibuildwheel to v3.3.1 for Python 3.14 support
• Monitor CI runs to verify Python 3.14 wheels build successfully

CI Failure Resolution

The build-wheels workflow was failing because cibuildwheel v2.21.3 doesn't support Python 3.14 (cp314).

Root Cause:

• Python 3.14 support was added in cibuildwheel v3.0+
• The workflow was using v2.21.3 which only supports up to Python 3.13

Solution:

• Upgraded to cibuildwheel v3.3.1 (latest stable version as of Jan 2026)
• This version includes full Python 3.14 support with cp314 ABI
• Existing manylinux2014 configuration remains compatible

Commit: Upgrade cibuildwheel from v2.21.3 to v3.3.1 for Python 3.14 support

@copilot All Build wheels / verify wheels for mac14, mac15, windows and ubuntu-latest failed. The copilot analysis is below.
The job failed because the wheel filename pattern wheelhouse/benpy--cp314-manylinux_x86_64.whl was referenced, but no matching wheel file was found, and the pattern itself is invalid. This resulted in the error: Invalid wheel filename (wrong number of parts): 'benpy--cp314-manylinux_x86_64'.

Solution:

Ensure your wheel build step (cibuildwheel) produces wheels for Python 3.14 and for the correct architectures (x86_64, manylinux).

Confirm your build matrix in .github/workflows/build-wheels.yml includes Python 3.14 as a supported version. cibuildwheel may not yet support Python 3.14 by default; check the official documentation or add python 3.14 explicitly.

The file pattern should be corrected in your test and install steps. Use glob matching that accurately reflects the naming convention for wheels:

bash
WHEEL_PATTERN="wheelhouse/benpy-*-cp314-manylinux_x86_64.whl"
Make sure the wheels directory contains a wheel with a valid filename matching this pattern.

If cibuildwheel does not yet generate cp314 wheels, update it or add a custom build step for Python 3.14.

By correcting your build matrix and wheel pattern, and ensuring Python 3.14 wheels are actually built, you will resolve this job failure.

Fixed in commit c5c34df. The issue was that cibuildwheel v2.21.3 doesn't support Python 3.14. Upgraded to v3.3.1 which includes full cp314 support. Python 3.14 wheels should now build successfully across all platforms.
