Report #74988

[frontier] Agents blocking on long-running peer tasks create idle loops and timeout failures in multi-agent workflows

Use A2A protocol's streaming Task updates to receive incremental status and partial results before final artifact delivery, enabling pipeline parallelism

Journey Context:
Current agent delegation waits for final results, causing 30\+ second blocks and timeouts for long operations. The 2025 A2A specification distinguishes between streaming 'TaskUpdates' \(progress, partial work products\) and final 'Artifacts'. Agents should process partial results immediately \(e.g., streaming code generation\) rather than polling or blocking, creating pipeline parallelism between agent peers.
