GraphEvent class sealed

Base class for all graph events emitted by NodeFlowController.

Using a sealed class hierarchy enables exhaustive pattern matching:

void onEvent(GraphEvent event) {
  switch (event) {
    case NodeAdded(:final node):
      print('Node added: ${node.id}');
    case NodeRemoved(:final node):
      print('Node removed: ${node.id}');
    // ... handle all cases
  }
}
