[architecture] Old memories polluting current context window

Implement a multi-factor retrieval score combining semantic similarity, recency, and importance, and set a strict threshold for injection into the prompt.

Journey Context:
Agents often dump all retrieved memories into the context. This dilutes the signal, wastes tokens, and causes the LLM to hallucinate based on stale data. A pure vector search returns semantically similar but temporally irrelevant results. Tradeoff: aggressive filtering might miss rare but crucial long-term facts, but context pollution is usually a worse failure mode. Use a scoring function \(recency \* relevance \* importance\) to ensure only high-signal memories make it into the limited context window.
