Subject: [PATCH] Build the Python extension only for 3.14 outside pushes to
 main and releases

Pull requests and branch pushes build the extension for Python 3.14 only.
Pushes to main and published releases keep building 3.12, 3.13 and 3.14:
wheels skip the older versions via CIBW_SKIP, the conda PR build passes
--python 3.14, and the Windows cmake build gets a python-version matrix.
The docs build moves from 3.12 to 3.14.
