Fix latest-version workflow check (#812)

## Summary
- make the latest-version workflow test use the action output for the
exact installed version
- allow `uv --version` to include additional platform/build metadata
- keep validating that the reported version matches the latest GitHub
release

## Testing
- npm ci --ignore-scripts
- npm run all
- actionlint .github/workflows/test.yml
