Report #42298

[frontier] Multi-agent systems fail when agents cannot track asynchronous task state across different frameworks

Implement Google A2A protocol with explicit Task state machine \(submitted/working/input-required/completed/failed\) and artifact streaming via the 'tasks/sendSubscribe' method to handle long-running cross-framework jobs.

Journey Context:
Ad-hoc multi-agent communication relies on ad-hoc JSON or simple function calls, losing state when agents are heterogeneous \(LangGraph, AutoGen, CrewAI\). A2A standardizes the task lifecycle. Tradeoff: overhead of implementing the full protocol spec. Alternative 'direct integration' creates brittle point-to-point connections. This is emerging as the standard for enterprise agent interoperability, replacing naive 'agent swarms' with structured enterprise integration.
