feat: add override icon search path for system tray

[mhduiy]

1. Changed resource prefix from /dsg/built-in-icons to /dsg-icon/ override in application-tray.qrc
2. Added DIconTheme include and modified DCI theme search paths in trayplugin.cpp
3. Prepended the override path to ensure system icons take precedence over theme icons
4. This allows system icons to remain consistent regardless of theme changes

feat: 为系统托盘添加图标覆盖搜索路径

1. 将 application-tray.qrc 中的资源前缀从 /dsg/built-in-icons 改为 /dsg- icon/override
2. 在 trayplugin.cpp 中添加 DIconTheme 包含并修改 DCI 主题搜索路径
3. 将覆盖路径前置以确保系统图标优先于主题图标
4. 这使得系统图标在不同主题下保持一致性

我来审查这段代码的变更，从语法逻辑、代码质量、代码性能和代码安全四个方面进行分析：

语法逻辑

1. 语法上没有问题，代码变更符合C++和Qt的语法规范。
2. 逻辑上，代码通过修改资源文件前缀并添加了图标主题搜索路径的设置，实现了图标资源的重定向。

代码质量

1. 资源文件前缀从"/dsg/built-in-icons"改为"/dsg-icon/override"，命名更加清晰明确，表明这是用于覆盖默认图标的资源。
2. 添加了DIconTheme头文件包含，这是一个良好的实践。
3. 代码结构清晰，初始化逻辑合理。

代码性能

1. 在init函数中，每次初始化都会获取和设置图标主题搜索路径，这部分可以考虑是否可以优化为一次性的初始化操作。
2. 使用prepend将自定义路径添加到搜索路径列表的前面，确保优先使用自定义图标，这是一个合理的性能考虑。

代码安全

1. 使用DIconTheme是安全的，它提供了标准的图标主题管理机制。
2. 路径操作使用了Qt提供的API，避免了直接的文件系统操作，减少了潜在的安全风险。

改进建议

1. 性能优化：可以将图标主题路径的设置移到类的构造函数或静态初始化部分，避免每次初始化插件时都重复设置。
2. 错误处理：可以添加对DIconTheme::setDciThemeSearchPaths返回值的检查，确保设置成功。
3. 资源管理：可以考虑使用RAII方式管理这些路径设置，确保在插件卸载时能够正确清理。

改进后的代码示例：

void TrayPlugin::init(PluginProxyInterface *proxyInter)
{
    m_proyInter = proxyInter;
    
    // 静态初始化图标主题路径
    static bool pathsInitialized = false;
    if (!pathsInitialized) {
        auto dciPaths = Dtk::Gui::DIconTheme::dciThemeSearchPaths();
        dciPaths.prepend(":/dsg-icon/override");
        if (!Dtk::Gui::DIconTheme::setDciThemeSearchPaths(dciPaths)) {
            qWarning() << "Failed to set DCI theme search paths";
        }
        pathsInitialized = true;
    }

    auto sniProtocol = new SniTrayProtocol();
    auto xembedProtocol = new XembedProtocol();
    auto indicatorProtocol = new DDEindicatorProtocol();
    // ... 其余代码
}

这样的改进可以避免重复设置路径，并增加了错误处理机制，提高了代码的健壮性。
