[The `uv` project](https://github.com/astral-sh/uv) includes a `uvx` binary,
which is an alias for `uv tool run`. See:
https://docs.astral.sh/uv/guides/tools
The project isn't yet installable from crates.io, but in the future we'll
either use this crate directly to provide the `uvx` binary, or we'll make it a
redirect to the crate provides the binary (similar to
[`rg`](https://crates.io/crates/rg)).
