- ElytraGenerator no longer hardcodes Modes.elytra(): the mode is passed
through the constructor (canonical (session, pointType, mode) plus two
convenience overloads); CloseGenerator/MinSpeed/Obstacle/SpeedDemon/
TimeTrial now declare their own mode, so getMode() is reachable
- Session.ChatType gets next(); ParkourUser gets setChatType(); SettingsMenu
gains a chat-scope cycle button (slot 15) so LOBBY_ONLY/PLAYERS_ONLY are
no longer dead branches
- ChatTypeTest covers the cycle order and wrap-around
- TODO.md: PROGRESS-8 records both fixes
