Fix model validation and set_memory_mode API compatibility

- Make createdBy, createdAt, updatedAt optional on Character and Memory
  models (API doesn't always return these fields)
- Fix set_memory_mode to fetch character name before updating (API
  requires name in PUT body)
- Bump version to 0.2.1
