The MessagePack source generator cannot resolve CultRecordRef<T> on its own and
emitted a broken formatter reference; MessagePackKnownFormatter on the open
generic did not change that. An explicit MessagePackFormatter per member is the
same formatter the cache resolver uses, so the wire stays a key string.

The MessagePack source generator emitted a broken formatter reference for the
CultRecordRef<T> reference members. Declaring CultRecordRefFormatter<> a known
formatter makes the generated resolver defer to the cache's own.

e420410f (D11) refuses a reference member whose CLR shape the cache cannot
walk; many:false needs CultRecordRef<T>. CultGeometryBuildRequest.DomainKey,
CultGeometrySelectedCutManifest.RequestKey and CultGeometryChunkArtifact.CutKey
were strings marked [CultReference], so registering the geometry catalog threw
and 7 geometry tests failed on main. All three are record keys of another
document, so the members become CultRecordRef<T> (the attribute is dropped, the
type declares the reference). The msgpack formatter writes a CultRecordRef as
its key string, so the wire bytes and the fingerprint inputs are unchanged.
