20250425 update
1. Fixed an issue where the help menu incorrectly displayed mines instead of unopened tiles in custom mode.
2. Updated the leaderboard refresh logic: leaderboard data is now refreshed in the background when opened, allowing players to return to the game or access other menus without waiting for the refresh to complete.
3. Fixed a potential issue where concurrent drawing from multiple threads could result in incorrect graphics rendering or window size.
