V310 - FIX FOR V309 FULL INSTALLER FAILURE
========================================

The V309 ZIP included a full account installer with an outdated V308
Join Game validation. It expected drakSubmitDirectIPJoin() directly in the
Join Game button. V309 instead uses drakV309StartDirectJoin() for that button.
Therefore SETUP_IN_GAME_ACCOUNTS.bat could show:
"V308 local LAN / direct Join Game UI was not installed."

TO APPLY ONLY THE MULTIPLAYER UI:
1. Close BaldurII.exe.
2. Run START_HERE_V310_MULTIPLAYER_UI_ONLY.bat.
3. Select the BG2 GAME installation directory (e.g. F:\Games\BG2 FULL EDIT CREATOR),
   NOT Documents/Baldur's Gate II - Enhanced Edition.
4. The installer updates ONLY game/override/UI.MENU; no character folders,
   router process or login flags are changed.

The full account setup script SETUP_IN_GAME_ACCOUNTS.bat is retained and now
accepts the current V309 LAN actions. It is NOT needed for this UI update.

NOTE: Native join behavior still requires in-game testing. Do not run the
full account installer with BG2 open. There is no automatic backup.
