[architecture] Treating long-term memory as append-only without an invalidation or update mechanism

Implement a 'memory update' pipeline: when a new fact is extracted, search for existing contradictory facts and either overwrite \(for mutable state\) or mark as superseded \(for historical tracking\) before inserting the new fact.

Journey Context:
If a user changes their preference from 'light mode' to 'dark mode', an append-only vector store will retain both. A future retrieval might surface the old preference. Vector stores are inherently additive. You must build an application-level reconciliation layer that identifies conflicting memories and updates or deletes the obsolete one, ensuring the agent acts on the current state of the world.
