python: support Python 3.14

[mathstuf]

Fedora Rawhide has it.

Note that 3.14 is left out of CI because the Github CI stuff in use doesn't support it yet.

LGTM. Let's wait until there's a release of Python 3.14 so we can quickly check that it really works as expected.

Expected release date: 2025-10-07

A pity that Github doesn't offer CI images that let folks test things before they're released to help fix bugs… But at least this can be pulled by other distros which ship Python 3.14 in the meantime.

You could also set up your own Docker image.

The expected date has passed; perhaps this can go now? I'll rebase for the conflicts.
