Report #65602

[frontier] Multi-agent systems locked into single vendor cannot interoperate across frameworks

Adopt Google A2A protocol with AgentCard discovery and Task/Artifact message passing for cross-platform agent handoffs

Journey Context:
Vendor lock-in prevents scaling agent teams; A2A defines HTTP\+JSON endpoints for capability discovery \(AgentCard\) and async task delegation \(Task/Artifact messages\), enabling heterogeneous agents \(Python/JS/Enterprise\) to collaborate without shared memory
