Route all core.info and core.warning calls through the new
log.info/log.warning wrappers so quiet:true suppresses them.
The ##[add-matcher] directive in setup-uv.ts uses core.info
directly since it is a workflow command, not user-facing output.
Update action.yml, action-types.yml, and README.md with the
new quiet input (default: false).
## 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
## Summary
- add top-level uncaughtException and unhandledRejection handlers for
the save-cache entrypoint
- report unexpected post-action failures through core.setFailed with
stack/context
- regenerate the committed save-cache bundle
