Chandler Carruth 76dd872ab4 Switch to prek rather than pre-commit (#7244)
This provides a native harness with several advantages over
`pre-commit`:

- Faster when initializing the cache
- Smaller cache sizes: under 43mb compared to over 62mb
- Better integration with `uv` for Python usage

Steps for migrating for existing contributors:

1.  Install `prek` following instructions in the updated docs.

2.  Replace hooks in an existing checkout with a special flag:

    ```sh
    prek install --overwrite
    ```

    The `--overwrite` flag is what removes the old hooks.

    If you used the pre-push variant:

    ```sh
    prek install --hook-type pre-push --overwrite
    ```

3.  Optional cleanups:

    ```sh
    rm -rf ~/.cache/pre-commit  # reclaim the old hook-environment cache
pipx uninstall pre-commit # if installed via pipx; or `brew uninstall
pre-commit`
    ```
