clearActiveEmbeddingIdentity method
Clears the active embedding identity (in-memory spec + persisted prefs).
See clearActiveInferenceIdentity: default throws rather than silently no-op'ing, so a non-overriding implementer fails loudly instead of leaving a stale persisted identity.
Implementation
Future<void> clearActiveEmbeddingIdentity() async {
throw UnimplementedError(
'clearActiveEmbeddingIdentity is not implemented by this ModelFileManager',
);
}
