Key Conflict Wheel

修复：1.20.1 版轮盘里所有按键都显示成「未指定」，现在跟 1.21.1 一样显示功能名（前进、跳跃、打开背包这类）。之前是我移植时取名字的方法用错了，读的是物理按键名，而轮盘一打开按键就被临时解绑，所以读不到。 变更：ESC 现在默认拉黑，按 ESC 不会再弹出轮盘，随时都能正常开菜单。老配置文件第一次启动会自动补上，不用手动改；想把 ESC 加回来的话，在 K 菜单里把它从拉黑表里去掉就行。

Fix: The 1.20.1 wheel showed "Not Bound" for every key. It now shows the action name (Forward, Jump, Open Inventory...) just like the 1.21.1 version - I had used the wrong method while porting, so it was reading the physical key name, which is unbound while the wheel is open. Change: ESC is now blacklisted by default, so it never opens the wheel and you can always get to the menu. Existing config files get this added automatically on the next launch; to let ESC open the wheel, just remove it from the blacklist in the K menu.
