StateSelection<TState extends BlocState> extension

Extension that adds state selection capabilities to JuiceBloc.

State selection allows you to observe only parts of state, avoiding unnecessary widget rebuilds when unrelated state changes.

Example:

// Only emits when count changes
bloc.select((state) => state.count).listen((count) {
  print('Count changed to $count');
});

// Combine multiple selectors
bloc.select((state) => state.user.name).listen((name) {
  print('User name: $name');
});
