Agent2Agent protocol: discovery, tasks and messages

The A2A specification describes how agents expose capabilities and exchange messages, tasks and artifacts. Its discovery and task-lifecycle sections provide a reference for evaluating interoperability between independently operated agents. The linked specification is maintained upstream; implementations should identify the edition they support.
