- Add state.SerializerConfig and state.NewSerializer for vertex serialization - Add state.Manager interface extending State with DAG operations - Add bootstrap.Config with all required interfaces (Blocker, Halter, LinearizableVM) - Add bootstrap.Bootstrapper implementing BootstrapableEngine - Add bootstrap/queue.Queue for job processing - Add getter.Handler and getter.Getter interfaces This enables the DAG consensus engine to be properly wired up in the node.
