What version of @langchain/langgraph do you have installed?

0.0.31

And it seems that it is still ok if I don't import 'Annotation' and don't use Annotation.Root() to define a state. So can I give up using it ?

And what should I do and how to write if I want to limit the type of a defined state using interface?
