InteractionState class

Contains all interaction-related state for the node flow editor.

This class manages the state for various user interactions including:

• Node dragging
• Connection creation
• Multi-node selection
• Mouse cursor state
• Pan/zoom control

All state is managed using MobX observables for reactive updates. The class provides both low-level observables and high-level convenience getters for accessing state.

Example usage:

final state = InteractionState();

// Check if user is dragging a node
if (state.currentDraggedNodeId != null) {
  // Handle drag
}

// Start a connection
state.update(
  temporaryConnection: TemporaryConnection(
    sourceNodeId: 'node-1',
    sourcePortId: 'port-1',
  ),
);
