Wire up scaleway/scaleway-cli as a watched package (extra's copy lags
weeks behind upstream). Getting a real second package running exposed
gaps uv's config never hit:
- asset_pattern/checksum_asset_pattern now support a {version}
placeholder for release assets that embed the version in the
filename (checker::version_from_tag strips a tag's leading `v`).
- same-origin-sha256 now matches the checksum line by filename instead
of assuming a single-hash file, to support combined multi-asset
checksum files like scaleway-cli's SHA256SUMS.
- latest_github_release now confirms each Atom-feed candidate against
the releases API instead of trusting the newest entry outright —
scaleway-cli publishes a `-dbg1` tag with no real Release object that
otherwise sorts newest in the feed.
Confirmed correct against the real repo: no attestations upstream, so
tier 4 (same-origin-sha256) applies, and the checker correctly skips
the dbg1 tag to land on the real latest release.
