平台注册表由 9 个扩到 15 个，同时补齐 sdk/types.ts 的类型与 OpenAPI 文档里的能力位声明。 - migu：命中 Z3D/I3D 加密候选时不返回直链，改由服务端解密代理出流， SDK 侧只负责登记票据，避免客户端拿到无法播放的密文 - apple：只提供 preview 试听片段（完整曲为 DRM），标 noAggregate 排除在跨平台精确匹配之外，防止用它顶掉其它平台的可播结果 - 其余平台按既有 PlatformModule 约定实现搜索/专辑/歌单/歌词 为什么合并成一次提交：六平台共用同一份注册表与能力位声明， 拆开会产生互相引用、单独无法通过类型检查的中间态。

// 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 }
