Make compatible with pipx?

I'm not too familiar with pipx, but I like how it describes a use case as "turning PyPI into an App Store for python".

- [ ] See if I can use pipx to install this project with an easier CLI entry point than the current implementation. (It shouldn't change current workflows, just make it easier for people who use pipx?)
- [ ] Add a note to documentation installation section that `pipx` can be used for system-wide installation.
- [ ] Also sort out how to install with uv. See reddit [conversation](https://www.reddit.com/r/Python/comments/1mfd3ww/but_really_why_use_uv/): "uv lets you `uv tool install` python-based tools into dedicated venvs, at the user-level. It manages the venv for you. It keeps that tools reps isolated. It lets you just snag it and run it." Look at [uvx]](https://docs.astral.sh/uv/guides/tools/).
