[architecture] Context window explosion from agents dumping all shared history into a single scratchpad

Isolate agent working memory and use scoped, namespaced queries to a centralized long-term memory store, rather than sharing a monolithic conversation history.

Journey Context:
To ensure agents 'know' what happened, developers often concatenate all agent messages into one massive shared history. This quickly exceeds context limits and degrades reasoning via the 'lost in the middle' phenomenon. Instead, agents should maintain isolated short-term memories. When cross-agent knowledge is needed, they should query a centralized vector store using scoped metadata filters \(e.g., namespace=project\_x\) to retrieve only the precise context required.
