 - **BREAKING CHANGE**: `SignalHook` no longer calls `setState` to trigger a rebuild when the signal changes. Instead, you should use `SignalBuilder` to listen to signal changes and rebuild the UI accordingly. This change improves performance and reduces unnecessary rebuilds. You can also use `useListenable` if you want to trigger a rebuild on signal changes.

   ### Migration Guide

   ```dart
   final count = useSignal(0);
   return Text('Count: ${count.value}'); // Auto-rebuilds

   return Text('Count: ${count.value}');
   ```

   This is inline with the behaviour of `useValueNotifier` from `flutter_hooks`.
