[architecture] Agent performance degrades due to context window pollution from irrelevant broadcast messages

Replace global broadcast with a publish-subscribe model using topic routing, or strictly use point-to-point messaging where only the targeted agent receives the message payload.

Journey Context:
To keep agents 'informed', developers often dump all inter-agent messages into a shared chat history. This quickly fills the context window with irrelevant noise, causing the LLM to ignore critical instructions \(the 'needle in a haystack' problem\). Agents should only receive the minimal context necessary to perform their specific task, similar to microservices isolating their domain data.
