[architecture] Over-stuffing the context window with retrieved documents instead of using a vector store for long-term knowledge

Use the context window strictly for operational state \(current task, recent turns, active tools\) and a vector store for episodic/semantic knowledge. Inject only the top-K most relevant facts into the context.

Journey Context:
Agents often try to cram entire knowledge bases into the prompt. This hits token limits, explodes costs, and degrades instruction-following due to the 'needle in a haystack' effect. Vector stores handle scale, but they are lossy and introduce latency. The right architecture is a two-tier system: fast, exact context for 'working memory' and approximate, scalable vector retrieval for 'long-term memory'.
