TagInputNotifier class
A ChangeNotifier that manages the state and behavior of tags in a TagField.
This class handles tag operations including adding, removing, validation, and duplicate checking. It notifies listeners when the tag list changes, enabling reactive UI updates.
Example usage:
final notifier = TagInputNotifier(tagFieldWidget);
notifier.addListener(() {
print('Tags changed: ${notifier.tags}');
});
