Fix code review issues

- Add agent_id parameter to client.add() and use it in mem0_conclude
- Fix inconsistent field access in queue_prefetch_and_get (check both text and memory)
- Remove unused _read_filters() and _write_filters() methods
- Mark prefetch() query parameter as deprecated (was unused)
