Switch Python to unstable and add pydantic-ai

Pydantic-ai is an agent framework that seems simple and good: well-typed with
pydantic, tool usage is just an `@tool` decorator on a function, and so
on. While building these I realized there were some deps they needed that were
already in nixpkgs unstable, so I just switched to that instead of trying to
backport all the versions and stuff.
