Add uv-run hook

We have a small python script with a handful of external dependencies which we want to run as a local pre-commit hook. To ensure that the dependencies are installed, it would be great to use PEP-723 inline script metadata and use `uv run --script` to execute the script.

Would it be possible to add a `uv-run` hook that would allow for this?
This would be helpful since we don't want our developer to have to install `uv` (as much as I love it of course :D), so ideally this would "just work" behind the scenes.

I am happy to submit a PR if that would be helpful.

Thanks!

(if there are other ways to do the thing outlined above I am all ears)

No files or tests are named in the issue. Start by inspecting how this repository defines existing pre-commit hooks and how dependencies are provisioned, then verify the expected behavior of uv run --script with PEP-723 metadata. Done means a uv-run hook can execute a Python script with inline dependencies without requiring developers to install uv separately.
