enableEdgeDocking static method

Future<bool> enableEdgeDocking({ required WindowEdge edge, double visibleWidth = 5.0, int hoverDelay = 300, })

启用窗口边缘停靠功能（类似QQ的停靠行为）

edge 要停靠到的边缘位置 visibleWidth 停靠时可见的窗口宽度（像素），默认为5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. 将窗口移动到指定边缘，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，重新隐藏到边缘

Implementation

  required WindowEdge edge,
  double visibleWidth = 5.0,
  int hoverDelay = 300,
}) async {
  if (!MyPlatform.isDesktop) return false;

  try {
    final display = await screenRetriever.getPrimaryDisplay();
    if (display.visiblePosition == null || display.visibleSize == null) {
      return false;
    }

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

    // 计算停靠位置
    Offset dockPosition;
    switch (edge) {
      case WindowEdge.left:
        dockPosition = Offset(
          workAreaPosition.dx - windowSize.width + visibleWidth,
          workAreaPosition.dy + (workArea.height - windowSize.height) / 2,
        );
        break;
      case WindowEdge.right:
        dockPosition = Offset(
          workAreaPosition.dx + workArea.width - visibleWidth,

        dockPosition = Offset(
          workAreaPosition.dx + (workArea.width - windowSize.width) / 2,

        );
        break;

        dockPosition = Offset(
          workAreaPosition.dx + (workArea.width - windowSize.width) / 2,
          workAreaPosition.dy + workArea.height - visibleWidth,
        );
        break;
    }

    // 移动窗口到停靠位置
    await windowManager.setPosition(dockPosition);

    // 启动鼠标位置监听
    _startMousePositionMonitoring(
      edge: edge,
      dockPosition: dockPosition,
