// 阿里系单元服务实例（由 provider_registry.go 按服务池字段构造）：
// 转写=DashScope 录音文件转写（paraformer-v2，异步）、翻译=阿里翻译。
// 总结（通义千问）走 OpenAI 兼容端点，见 provider_registry.go 的 openaiSummarizer。
//
// 语言支持过滤已上移到编排层：服务池 asrfile_alibaba 模板的 languages 字段 seed 了
// paraformer-v2 实际支持的语种，选路时不支持的语言会跳过本服务（原 SupportsLanguage 白名单
// 的职责由后台配置接管——把西语送进 paraformer-v2 会静默返回空转写，务必别放开 languages）。
