Update ci uv+py311

[jeromekelleher]

Drop Python 3.10 and migrate to using a single uv lockfile to fully pin dependencies on CI/CD. This should make maintenance easier because running uv lock periodically should do the trick and it should prevent CI from breaking due to transitive dependencies.

Closes #3383
Closes #3368

Mostly working OK. Sticking points:

• Docs - this is quite complicated
• circleCI. Would be nice if we could port this all over to GitHub actions
• Something weird on windows 3.14.
• 3.14 is generally much too slow because of (I think) pins on Zarr < 3.

I'm going to switch to tszip now as it's a simpler project and generally a blocker on progress now.
