  /**
   * Marker interface for responses emitted by streaming message operations.
   * 
   * This interface serves as a common type for all possible response objects that can be
   * emitted in a streaming context when sending messages to an agent. The streaming
   * response can include various types of objects:
   * 
   * - Message objects: Immediate responses or intermediate messages
   * - Task objects: Task creation or final task state
   * - TaskStatusUpdateEvent objects: Status changes during task execution
   * - TaskArtifactUpdateEvent objects: Artifact updates during task processing
   * 
   * This design enables type-safe handling of heterogeneous streaming responses while
   * providing flexibility for the A2A protocol's asynchronous communication patterns.
   * Clients can use pattern matching or type checking to handle different response
   * types appropriately in the streaming context.
