[architecture] Appending new memories creates duplicates or contradictions with existing long-term memory

Implement an upsert logic for semantic memory. Before writing a new fact, perform a targeted search for existing facts about the same entity. If a conflicting fact exists, delete or update the old fact rather than inserting a new one.

Journey Context:
Most agent memory implementations just append new embeddings. If a user says 'I moved to Seattle' and later 'I moved to Austin', both facts get retrieved, and the agent gets confused. Memory requires curation. A write-through cache or upsert mechanism \(checking before writing\) is computationally heavier but essential for maintaining a consistent world model and preventing context window pollution by contradictions.
