[architecture] Agent recalling irrelevant details from past sessions while ignoring recent context

Apply a time-weighted decay factor to memory retrieval scores and implement an eviction policy for low-importance, old memories.

Journey Context:
Vector similarity search is time-agnostic. A memory from 6 months ago about a deprecated API might have high cosine similarity to a current query, polluting the answer. Without decay, the memory store grows indefinitely, degrading retrieval performance and increasing storage costs. The tradeoff is that aggressive decay might forget long-term preferences, so decay must be modulated by an 'importance' score assigned at write time. High importance \(e.g., user's core preference\) resists decay; low importance \(e.g., temporary file path\) decays rapidly.
