Detailed Description

GraphNode that delegates work to a remote A2A agent.

Mirrors the role MCPCallerNode plays for tool servers. On execute(), the node:

1. Reads prompt (or a configured key) from the GraphState.
2. Calls message/send on the configured A2AClient.
3. Writes the agent's response back into the configured output key.

Send fan-out works transparently: many A2ACallerNode instances sharing one A2AClient produce concurrent HTTP requests via the async executor. Each call is independent — no shared state in the client.
