fix(discord): extend bot-task cancellation to connect()'s generic exception branch

Follow-up to #44389: the generic 'except Exception' branch in connect()
had the same orphaned-task hazard as the timeout branch. Extract the
cancel-and-await logic into _cancel_bot_task() and call it from all
three sites (timeout branch, exception branch, disconnect()).

Also adds deaneeth to AUTHOR_MAP.
