[architecture] Decentralized peer-to-peer agent communication leads to unpredictable states and untraceable failures

Use a centralized orchestrator \(hub-and-spoke\) topology for multi-agent coding systems, restricting peer-to-peer communication to strictly defined, stateless interactions.

Journey Context:
Fully autonomous peer-to-peer agents sound cool but are a nightmare to debug. When a failure occurs, you cannot trace the call stack. A centralized orchestrator maintains the global state, routes messages, and handles errors. Tradeoff: orchestrator becomes a single point of failure and bottleneck. Alternative: event-driven mesh, but hub-and-spoke is far easier to observe and control for deterministic coding tasks.
