Epic Fight - Better lock on

-优化了第三人称下的玩家模型渲染，现在在狭窄的区域中，玩家模型会逐渐透明。
-添加了自动切换第一人称的配置，当摄像机距离玩家过近时，会切换至第一人称

-Optimized the rendering of the player model in third-person view. The player model will now gradually become transparent when in cramped/narrow areas.
-Added a configuration option for automatically switching to first-person view. When the camera gets too close to the player, the view will automatically switch to first-person.
