[architecture] Retrieved memories from past sessions are polluting current task with irrelevant stale state

Apply temporal decay weighting to memory retrieval scores and explicitly tag memories with session IDs and timestamps. Boost recent memories, and require exact temporal matches for stateful data \(like 'file X was deleted'\).

Journey Context:
Vector similarity alone ignores time. A memory like 'user prefers dark mode' is evergreen, but 'the server port is 8080' is highly volatile. If you just do semantic search, old state overrides new state. Manual deletion is unscalable. The right call is hybrid search combining semantic similarity with recency decay \(e.g., exponential decay on timestamps\) and hard metadata filters for transient state.
