## Summary
Add a new boolean input `download-from-astral-mirror` (default: `true`)
that controls whether uv is downloaded from the Astral mirror or
directly from GitHub Releases.
When set to `false`, the mirror rewrite is skipped entirely and the
download goes straight to GitHub Releases.
Closes: #870
