[architecture] Retrieving outdated memories that contradict the current application state

Implement state-aware memory invalidation by tagging memories with entity IDs and versioning, and delete or archive memories when the underlying entity state changes.

Journey Context:
Vector DBs retrieve based on semantic similarity, not temporal validity. If a user changes their preference from 'dark mode' to 'light mode', a naive vector search might retrieve 'user prefers dark mode' because it's semantically close to the query. Agents commonly append new memories without removing old ones. The tradeoff is append-only \(easy, but pollutes\) vs. upsert/invalidate \(harder, requires entity extraction, but keeps memory clean\). The right call is entity-based upsertion or explicit invalidation rules.
