Test speed ups

First I'm tying DNS caching to see if it's a DNS issue.

An improvement - but it's not using the cassette (?)

Hey @mskarlin - tried a few variants. 21d703f uses python from a uv venv, same poor performance (canceled after 10 minutes) and 0c7c64f uses actions/setup-python and gets same poor performance. Only other python to try I guess would be system python, but it's 3.10 on our runners. Not sure what else to try?

Yea we can just build the requirements.txt via uv export then use the system python & upgrade it like:

      - name: Set up Python ${{ matrix.python-version }}
        uses: actions/setup-python@v5
        with:
          python-version: ${{ matrix.python-version }}
          cache: pip
      - run: pip install .

Then the system python would be what we use. We can return to using uv for tests after we figure this out.

That's pretty much 0c7c64f - except uv did the pip install.

I tried to not use uv for doing the pip install, but that's not compatible with our pyproject.toml. I think it's pretty unlikely that installing system packages with uv would impact performance - but we can try locally committing a requirements I guess

Ok @mskarlin - I completely purged uv so it's not used for parsing toml file, for pip install, or for python management. Completely clean in b2c1e33. We'll see how long the tests take. Edit: I've determined uv has no effect
