[frontier] Multi-agent systems become spaghetti code with hardcoded orchestration

Adopt AutoGen v0.4's event-driven architecture with state machines and message brokers instead of direct agent-to-agent calls

Journey Context:
Early multi-agent frameworks used nested chat loops or DAG-based orchestration, creating tight coupling. AutoGen v0.4 \(late 2024\) introduced an event-driven core where agents are state machines that emit and subscribe to events via a message broker. This enables decoupled 'agent societies' where agents react to domain events without knowing specific implementations. The pattern supports dynamic group chat formation, load balancing across agent pools, and failure isolation. It replaces the 'master coordinator' anti-pattern with distributed event sourcing.
