EffectScopeImpl class

Implementation of EffectScope for managing the lifecycle of effects and other reactive nodes.

This is the concrete implementation of the EffectScope interface. EffectScope allows you to group related effects together and dispose them all at once. It's useful for component-based architectures where you want to clean up all effects when a component is destroyed.

See EffectScope for the public interface and usage examples.

Example:

final scope = EffectScope()
  ..run(() {
    final signal = Signal(0);
    Effect(() => print('Value: ${signal.value}'));

    // Both signal and effect will be disposed when scope is disposed
  });

// Later, dispose all effects in the scope
scope.dispose();
