[architecture] Central orchestrator agent becomes a latency bottleneck and single point of failure

Replace the synchronous central orchestrator with an asynchronous event-driven architecture \(Pub/Sub\) where agents subscribe to event types and act independently, using a blackboard for shared state.

Journey Context:
The simplest multi-agent architecture is hierarchical: an Orchestrator LLM receives the task, delegates, waits, and synthesizes. This is slow \(sequential LLM calls\) and fragile \(if the orchestrator hallucinates, the whole pipeline fails\). Shifting to an event-driven model \(Agent A emits CodeWrittenEvent, Agent B listens and runs tests\) parallelizes execution and removes the orchestrator bottleneck. The tradeoff is harder debugging and less deterministic flow, but massive gains in throughput and resilience.
