Migrate from poetry to uv

[da1910]

Migration to a more modern build and packaging system

• Swap setup to uv
• Swap to ruff for lint and formatting
• Fix some ruff and mypy complaints

Good to see the code-style check working. We've had issues with other repos because development dependencies aren't installed by the action when using uv, but it's working here because you're using uv run.

@da1910 Does uv run use the version of mypy specified in pyproject.toml? Or does it just download and install the latest version?
