[architecture] Old tasks or irrelevant facts polluting agent context in new sessions

Implement strict memory scoping and isolation. Use episodic memory bounded by session ID, and only promote specific, distilled facts to semantic long-term memory. Always prepend current task instructions over recalled memories.

Journey Context:
When agents share a single long-term memory pool, retrieving top-k vectors might pull in contradictory or obsolete facts from past sessions \(e.g., 'user prefers dark mode' when they just asked to switch to light mode\). People treat vector DBs as a dumping ground. The tradeoff is recall breadth vs. precision. The right call is to separate episodic \(what happened\) from semantic \(what is true\), and apply a recency decay or strict metadata filtering \(e.g., session\_id, task\_id\) to prevent cross-contamination.
