fix: reduce app item border width

[wjyrich]

Changed the border width of the app item from 2px to 1px to create a more subtle and visually appealing appearance. The previous 2px border was too prominent and created visual clutter in the task manager interface. This adjustment improves the overall aesthetic by making the border less obtrusive while still maintaining the visual separation between app items.

Influence:

1. Verify app items in the dock display with thinner borders
2. Check that the border is still visible but less prominent
3. Test hover and active states to ensure border visibility is appropriate
4. Verify the change doesn't affect the layout or spacing of app items
5. Test with different themes to ensure consistent appearance

fix: 减小应用项边框宽度

将应用项的边框宽度从2像素改为1像素，以创建更微妙和视觉上更吸引人的外观。
之前的2像素边框过于突出，在任务管理器界面中造成了视觉混乱。此调整通过使
边框不那么突兀来改善整体美观性，同时仍保持应用项之间的视觉分隔。

Influence:

1. 验证坞站中的应用项是否显示更细的边框
2. 检查边框仍然可见但不太突出
3. 测试悬停和活动状态，确保边框可见性适当
4. 验证更改不会影响应用项的布局或间距
5. 使用不同主题测试以确保外观一致

Hey there - I've reviewed your changes - here's some feedback:

• Consider binding the border width to a theme or shared style constant instead of a hard-coded 1, so that the appearance can be tuned consistently across different components and themes.
• You may want to verify that a fixed 1px border scales well on HiDPI displays; if not, using Qt.devicePixelRatio or a scalable unit could keep the border visually consistent.

我来对这段代码变更进行审查：

1. 语法逻辑：

   • 代码语法正确，这是一个简单的属性值修改，将边框宽度从2改为1
   • 修改不会影响代码的语法正确性和逻辑结构

2. 代码质量：

   • 修改是合理的，将边框宽度从2px减小到1px可以让界面看起来更加精致
   • 建议考虑将这个数值抽取为一个常量或属性，方便统一管理和修改
   • 例如可以添加：property int borderWidth: 1

3. 代码性能：

   • 这个修改对性能影响微乎其微
   • 较小的边框宽度实际上可能会略微提升渲染性能，因为需要绘制的像素更少

4. 代码安全：

   • 这个修改不涉及任何安全问题
   • 纯UI层面的改动，不会影响应用程序的安全性

建议：

1. 考虑将边框宽度值提取为一个属性，便于维护和统一管理：

Item {
    property int borderWidth: 1
    
    Rectangle {
        border.width: borderWidth
        // ...
    }
}

2. 如果这个边框样式在其他地方也会使用，建议将其抽取为一个独立的组件，提高代码复用性。

总的来说，这是一个简单合理的UI优化修改，可以让界面看起来更加精致。
