[architecture] Appending new memories without invalidating contradictory old memories, leading to conflicting facts

Implement an upsert pattern for semantic memory: before inserting a new fact, search for semantically similar existing facts. If a contradiction or exact update is found, delete/overwrite the old memory before inserting the new one.

Journey Context:
Vector stores are append-only by default. Agents naturally learn new things that supersede old things \(e.g., 'User prefers Python' vs. old memory 'User prefers JavaScript'\). If you don't build a curation/update step into the memory write path, the DB fills with contradictions, and retrieval becomes non-deterministic, causing the agent to flip-flop between outdated and current facts.
