InferStateType

Unwrap the state shape from a compiled graph, a create-agent brand, or a plain type. Used by useStream<T>() to resolve T = typeof agent into the state the values/messages projections observe.

Structurally identical to the legacy @langchain/langgraph-sdk/ui helper of the same name; kept here as a framework-facing re-export so bindings can import from the stream subpath without needing the UI module.
