The signature of a reducer function is `(Value, Value) -> Value`.
!!! warning
`StateGraph` is a builder class and cannot be used directly for execution.
You must first call `.compile()` to create an executable graph that supports
methods like `invoke()`, `stream()`, `astream()`, and `ainvoke()`. See the
`CompiledStateGraph` documentation for more details.
Args:
state_schema: The schema class that defines the state.
context_schema: The schema class that defines the runtime context.
