Describe the problem

Currently, GuessInput is implemented as a StatelessWidget. Consequently, every state change triggers a rebuild that creates an entirely new text input instance. This prevents _focusNode.requestFocus() from taking effect, which is not the intended behavior for this tutorial.
This can be resolved when converting this into a StatefulWidget.

Expected fix

Convert the GuessInput class into a StatefulWidget.
