§81's "materials and shader nodes": a named
ShaderOperatorRegistry of operator factories.
Not revocable — the registry has no removal. The shader-graph IR stays a
closed union; this token hands over a place to register named factories
that produce closed nodes, not a way to widen the union (RFC 0001
alternative E's named-hook half).
