Sprout class abstract

A Seed whose branch holds its state in hooks declared inline in build — the hooks-style alternative to StatefulSeed + State<T>.

Subclass it and override build, calling context.useState / useStream / useEffect / useMemo to declare state. The subclass type is the reconcile tag, so two Sprouts of different subclasses never update into one another; state persists on the branch across config updates, keyed by call order.
