Always-on. Flags Relationships whose relating and related
objects are the same. Self-refs are advisory by default;
relationshipTypeBinding promotes them to errors when
the schema explicitly forbids self-reference for that type.
Dangling-reference checks aren't included — DataModel's
builders (createRelationship, createObject) reject unknown
ids at construction time, so a dangling endpoint can't exist
in a live DataModel.
