- 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）

// 网易云链接解析（上游 music-lib/netease/song.go 的 Parse 移植）
|
||
// 歌曲链接形态：
|
||
// https://music.163.com/#/song?id=29732995
|
||
// https://music.163.com/song?id=29732995
|
||
// https://music.163.com/song/29732995
|
||
// 裸数字 id 也接受（补充便利；上游仅接受链接）
|
||
// 直链 url/type 为尽力附带，失败不影响元数据返回（与上游一致）；
|
||
// 歌单/专辑链接抛清晰错误，提示使用对应 parsePlaylist/parseAlbum。
