build: remove setup.py and other build changes

[jandom]

Summary

This PR provides changes to gradually harmonize some of the build process. Less moving pieces, and closer to best practices.

Changes

• remove setup.py, this basically bypassed the messy deps in pyproject.toml but there are better ways to accomplish the same (pip install --no-deps .)
• refactor requirements-test.txt into pyproject.toml, using pip "dependency group" to bake this into pyproject.toml and install only the test deps without the main deps
• ignore .pre-commit-config.yaml because it's personal for now
• add uv so that we can take advantage of of 'dep groups' in pyproject.toml
• separate yaml and lock files for linux-64 and osx-arm64 (experimental, we shouldn't support Mac for now)

Related Issues

The 'main' deps declared in pyproject.toml will break the production environment. I've confirmed that setup.py route only worked because it skipped all the deps declared in pyproject.toml :)

Testing

Locally all dandy, launching a test job now.
