Module transport 

Transport abstraction for A2A client requests.

The Transport trait decouples protocol logic from HTTP mechanics. A2aClient holds a Box<dyn Transport> and calls Transport::send_request for non-streaming methods and Transport::send_streaming_request for SSE-streaming methods.

Two implementations ship with this crate:

Type	Protocol	When to use
JsonRpcTransport	JSON-RPC 2.0 over HTTP POST	Default; most widely supported
RestTransport	HTTP REST (verbs + paths)	When the agent card requires it

Re-exports
