v1.0.5

Fixed

• A page load requested the activity's own stylesheet manually, on top of the copy Moodle
  already loads automatically for every plugin — a harmless but unnecessary duplicate request,
  flagged by a Moodle Plugin Directory review.
• Round state (the current word, guesses so far, hint, timer) moved from the raw session
  object to Moodle's Cache API in session mode, the platform's recommended approach for this
  kind of per-student data — no change in behaviour for players.
