SetSignal<E> class abstract interface

Interface for reactive set signals.

SetSignal extends Signal to provide full Set functionality while maintaining reactivity. All set operations (add, remove, clear, etc.) will trigger notifications to subscribers.

Example:

SetSignal<String> tags = SetSignal({'dart', 'flutter'});

Effect(() => print('Tags: ${tags.join(', ')}'));
tags.add('reactive'); // Triggers effect
