Fun with uv and PEP 723

uv has been fantastic to use for little side projects. Combining uv run with `uv tool run` AKA `uvx` means one can fetch, install within a VM, and execute Python scripts from Github super easily. No git clone, no venv creation + entry + pip install.

And uv is fast — I mean REALLY fast. Fast to the point of suspecting something went wrong and silently errored, when it fact it did just what I wanted but 10x faster than pip.

It (and especially its docs) are a little rough around the edges, but it's bold enough and good enough I'm willing to use it nonetheless.

Truly. uv somehow resolves and installs dependencies more quickly than pyenv manages to print its own --help output.
