explain: route metadata-blob prefetch through refs.Primary

b3904df→main·

pfleidi·1mo ago·1 file·+14 added/-4 removed

loadV1MetadataRootTree is renamed to loadPrimaryMetadataRootTree and takes CommittedRefs. The origin remote-tracking fallback is gated on Read == Primary && PrimaryFetchableFromOrigin so the local-only mirror ref skips it.
