Report #24641

[frontier] Sequential agent loops blocking on slow tool calls and losing async context

Migrate to AutoGen v0.4 Core's event-driven AgentRuntime with async message passing; decouple agent logic from execution loop using Agents as event handlers

Journey Context:
Older patterns use while-loop agent.run\(\) blocking execution and preventing cancellation. AutoGen 0.4 introduces Actor-model runtime where agents are event handlers processing messages asynchronously. Enables true parallelism, easier cancellation, and fault isolation. Common mistake: trying to force sync patterns into async runtime or managing state manually instead of using AgentRuntime state stores.
