Report #81782

[frontier] Synchronous agent frameworks blocking on slow I/O, preventing parallel tool execution and concurrent agent collaboration

Adopt an actor model architecture \(AutoGen v0.4\+\) where agents are independent actors communicating via async message passing. Use \`send\` and \`receive\` primitives with message queues, enabling agents to work in parallel and handle back-pressure via mailbox semantics.

Journey Context:
Traditional agent frameworks run tools synchronously in a single thread, wasting time on I/O and preventing true collaboration \(Agent A cannot work while Agent B waits for an API\). The actor model \(Microsoft's AutoGen v0.4 rewrite\) treats each agent as an independent process with a mailbox. Agents send messages \(function calls, results, instructions\) asynchronously and continue processing. This enables true parallelism \(multiple agents working on sub-tasks\) and fault isolation \(one agent crashing doesn't kill the orchestrator\). This replaces sequential \`while True: action = agent.run\(\)\` loops with distributed agent systems.
