Restores the signed v1.7.126-alpha manifest to main now that both artifacts are
confirmed fetchable end-to-end:
- archipelago HTTP 200, sha256 matches the manifest
- frontend tarball HTTP 200, sha256 matches the manifest
The earlier publish was rolled back (e346e552) because the manifest went live
before its assets resolved. Two separate asset faults, now fixed: the binary's
first upload landed corrupt server-side and returned 500 on download (deleted
and re-uploaded, clean); the tarball's first upload returned an empty response
and never attached (re-uploaded, 201, full 210 MB).
This is byte-for-byte the manifest the tag already carries, so its signature is
unchanged and re-verified against the pinned release root.
