- 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）

// JOOX 歌词（上游 joox/lyric.go 移植）
|
||
// 端点：GET https://api.joox.com/web-fcgi-bin/web_lyric?musicid=<id>&country=sg&lang=zh_cn
|
||
// 响应形如 MusicJsonCallback({"code":0,"lyric":"<base64>"})，lyric 为 base64 UTF-8 歌词。
|
||
// 实测（2026-10-02）该旧接口仍可用（web_get_songinfo 已 404，但 web_lyric 未下线）。
|
||
// 兜底：openjoox2 /track 详情的 lrc_content（同为 base64），旧接口失败时使用。
|
||
// 解码：base64 → UTF-8 → HTML 实体（& 等）→ { lyric, tlyric: '' }
|
||
// 统一接口约定：{ promise, cancelHttp }；promise resolve → { lyric, tlyric }
