[architecture] Stuffing all conversation history into the LLM context window vs. dumping everything into a vector store

Implement a tiered memory architecture: working memory \(context window\) for the current task/recent turns, and long-term memory \(vector store\) for cross-session/factual recall. Only promote data to working memory via targeted retrieval.

Journey Context:
Working memory is fast but constrained by token limits and attention dilution. Vector stores scale infinitely but suffer from approximate retrieval and loss of temporal ordering. The tradeoff is latency/accuracy vs. capacity. The right call is keeping the context window lean \(only what is immediately necessary\) and using retrieval to populate it on demand.
