Project scaffold overhaul

[gabe-l-hart]

Description

This PR overhauls the build and dev system for the project to use modern tools (uv, hatch-vcs) and CI.

AI Usage

This was built mostly using OpenCode with qwen3.5:122b.

Initial Prompt

This is an old project with an old build/release system. I need to update it to use modern pyproject.toml instead of setup.py/requirements.txt. You can find an example of a similar project that was updated in the same way at ../py-to-proto.
Specifically, I want you to do the following:

1. Create a pyproject.toml that replaces setup.py, requirements.txt, and requirements_test.txt
2. Remove the Dockerfile
3. Update all scripts in scripts to not use the dockerized build env and instead use uv (also delete any scripts that are no longer relevent)
4. Overhaul the CI in .github/workflows to use uv and standard GitHub Actions (you can look at ../py-to-proto/.github/workflows for examples)
5. Update all docs to reflect using uv as the build env tool of choice
