Report #16606

[architecture] Agent writes conflicting memories that contradict each other, causing erratic behavior

Implement an 'update-or-insert' pattern in the memory write path: search for existing memories semantically similar to the new insight before writing, and update the existing memory rather than appending a duplicate.

Journey Context:
If a user says 'I use Python', the agent saves it. Later the user says 'I switched to Rust', the agent saves that too. Now retrieval yields conflicting instructions. The memory write path must first query the store for overlapping concepts. If an existing memory is found, the agent must generate an updated version \(e.g., 'User uses Rust \(switched from Python\)'\) and overwrite the old one, rather than naively appending.
