enableCornerDocking static method

Future<bool> enableCornerDocking({ required WindowCorner corner, double visibleSize = 20.0, int hoverDelay = 300, })

启用角落停靠功能（类似QQ的角落停靠行为）

corner 要停靠到的角落位置 visibleSize 停靠时可见的窗口尺寸（像素），默认为20x20像素 hoverDelay 鼠标悬停多久后显示窗口（毫秒），默认300毫秒 返回 true 表示启用成功，false 表示启用失败

此功能会：

1. 将窗口移动到指定角落，大部分隐藏，只留小部分可见
2. 监听鼠标位置，当鼠标悬停在可见部分时显示完整窗口
3. 当鼠标离开窗口区域时，重新隐藏到角落

Implementation

  required WindowCorner corner,
  double visibleSize = 20.0,
  int hoverDelay = 300,
}) async {

    }

    final windowSize = await windowManager.getSize();
    final workArea = display.visibleSize!;
    final workAreaPosition = display.visiblePosition!;

    // 计算停靠位置（角落位置，大部分隐藏）
    // 角落停靠时露出一个L形区域，比正方形更容易找到
    final cornerVisibleWidth = visibleSize * 2; // 水平方向可见宽度
    final cornerVisibleHeight = visibleSize; // 垂直方向可见高度

    Offset dockPosition;
    switch (corner) {
      case WindowCorner.topLeft:
        dockPosition = Offset(
          workAreaPosition.dx - windowSize.width + cornerVisibleWidth,
