* All logging is now in JSON lines format!
* Fixed a bug where the session summary was generated twice for the same session
* Fixed a reversion in the exit handling when the user logged out gracefully.
* Session summaries now occur both at normal session termination (e.g., the user gracefully logs out) or abnormal termination, such as if the client disconnects suddenly.
* Now encode the AI results as UTF-8 instead of ASCII, because it would ocassionally send back non-ASCII characters which caused the server to throw errors
