Add support for Python 3.14

[hugovk]

The reason for #123 is to be able to support Python 3.14.

Rye doesn't support 3.14 and won't either:

$ echo 3.14 > .python-version
$ rye sync
error: Unable to determine target virtualenv Python version

So this PR requires #123 to be merged first, and then a merge or rebase from main.

Thanks, appreciate it. Once I've resolved #125 I'll drag this in.

Just to update: as of now #123 makes publishing harder (well, it broke it, but I can see how to fix it after a fashion: #125) and makes it hard for me to trust the process. I'm currently trying to decide if I should revert #123 or find better tooling that would let me manage a Python project and make use of 3.14.

I'd love to take this on but, at the moment, because of the impact #123 has in terms of needing to take on a new approach to maintaining Hike at a time when I don't have the time to learn a bunch of new things... sorry, I can't easily merge this at the moment. :-/

For now I'll have to hope the code's all good with Python 3.14 and, meanwhile, figure out how to migrate off rye and find something hopefully trustworthy and stable.

That's okay. Just seeing the CI pass here for 3.14 is confirmation that things are looking good for 3.14 👍

Right, I think, hope, I've wrangled uv such that I can still publish to test PyPI and eventually actual PyPI. So...
