- 删除旧 sdk/request.ts，全部 import 收敛到 sdk/common/request.ts（85 文件） - 注释死代码 630+ 行、裸 console.log 吞错 6 处、未使用符号 26 处清零 - bili 状态校验去重；utils DNS 预解析失败日志改 warn 带上下文 - CODE-AUDIT.md：第四节 P2 清理记录 + 第八节线索逐条复核结论（kw/kg/tx/wy parse 骨架相似实质各异，不抽公共层）

// QQ音乐链接解析（上游 music-lib/qq/song.go 的 Parse 移植）

// 歌曲链接形态：
|

// https://y.qq.com/n/ryqq/songDetail/<songmid>
|
||
// https://y.qq.com/n/yqq/song/<songmid>.html

// https://i.y.qq.com/v8/playsong.html?songid=<数字 id>（先反查 songmid）

// ...?songmid=<songmid>
|

// 返回 Song（含 songmid）；直链 url/type 为尽力附带，失败不影响元数据返回（与上游一致）。
