refactor: Migrate to PEP621, add uv.lock

This makes packaging easier on newer systems and facilitates
reproducibility of the builds.

Note: I do not have the expertise around setup.py & python packaging in
general. Part of this commit has been co-developed with an LLM.
I checked it works on my system.
