- Replaced deprecated _add_existing_weight implementation that previously relied on unsupported arguments (experimental_autocast, getter) removed in Keras 3.x. - Introduced custom weight lists (_hub_trainable_weights, _hub_non_trainable_weights) instead of using the deprecated _track_variable approach. Overrode trainable_weights and non_trainable_weights properties to properly expose hub weights to the Keras layer system. - Resolves the ValueError: Only instances of keras.Layer can be added to a Sequential model and related integration failures when using hub.KerasLayer in Sequential/Functional models.
