主要实现
1.使用WASD或方向按钮控制游戏
2.最高值4096，玩到4096视为胜利
3.随机生成2、4、8方块
4.移动方块
5.合并方块
JS代码干了什么
初始化游戏界面：创建游戏板和控制按钮。
定义游戏相关变量：如棋盘大小、棋盘状态、得分等。
初始化棋盘：创建棋盘元素并添加到页面。
生成新的方块：根据一定概率生成 2、4 或 8 的方块。
更新棋盘显示：根据方块的值设置背景颜色。移动方块：根据用户操作或键盘按键，实现方块的上、下、左、右移动。
合并方块：在移动过程中，相同值的方块会合并。
处理游戏结束：判断是否无法再进行移动。
监听用户操作：通过点击按钮或键盘按键触发移动操作。
HTML布局
`game-container`游戏板块|`game-board`游戏棋盘板块 |`controls`游戏控制按钮版块
