[architecture] Attempting to overwrite bad memories by adding new contradictory memories, leading to conflicting retrieval results

Implement explicit memory deletion or invalidation. When a user corrects the agent, search for the conflicting memory, delete it, or mark it as is\_invalid: true in metadata, then write the new memory.

Journey Context:
LLMs are stateless; memory is an external append-only store. If a user says 'Actually, I use React, not Vue', appending 'User uses React' doesn't delete 'User uses Vue'. Both will be retrieved, and the LLM will be confused. Memory architectures need a mutable state layer, not just an append-only log.
