将所有29个services插件从RegisterPlugin()转换为高效的RegisterPluginWithPorts()注册方式： 核心优化： - 消除启动时1200+无用插件实例创建（25插件×47次调用） - 统一插件注册机制，移除性能较差的旧接口 - 优化插件存在性检查，使用O(1)查询替代实例化检查 技术改进： - 移除旧RegisterPlugin()函数，简化代码路径 - 所有service插件使用统一高效注册方式 - 保持业务逻辑和外部接口完全不变 性能提升： - 显著减少启动时间和内存占用 - 消除重复的"加载了175个AV产品信息"日志输出 - 插件系统响应更快，扫描启动更迅速 影响范围：29个services插件全部完成转换 向后兼容：保持所有现有功能和接口不变
