v0.3.1 changelog

Added

• Added official A2A references covering the latest specification, Google launch post, Linux Foundation project governance, and GitHub project.
• Added A2A boundary mapping for Agent Card, task ids, context ids, messages, artifacts, streaming, push notifications, and in-task authorization.
• Added A2A peer-task fields such as native_protocol, remote_task_id, remote_context_id, agent_card_ref, delivery_mechanism, native_status, and remote_artifact_refs.
• Added remote channel peer-task events for linking and updating remote peer tasks.

Changed

• Clarified that A2A is a peer interoperability reference, not a replacement for Agent Runtime execution facts.
• Expanded remote channel identity, ingress, recovery, and anti-pattern guidance around peer protocols.
• Clarified that durable outputs should use artifact refs instead of messages.
