snowy-yang 33b96f92c4 feat(sdk): 新增咪咕/千千/JOOX/哔哩哔哩/5sing/Apple Music 六平台
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。

// Apple Music 歌词(上游 apple.go GetLyrics)
// 通道:amp-api /v1/catalog/<sf>/songs/<id>?include=lyrics&extend=extendedAssetUrls
// → data[0].relationships.lyrics.data[*].attributes.ttml
// 上游取到的是 TTML(Apple 逐字歌词格式,非 LRC),原样放入 lyric 字段返回;没有则忠实返回空串。
// 注意(2026-10 实测):匿名 developer token 请求时 Apple 不返回 lyrics relationship
// (即使 attributes.hasLyrics=true,歌单/搜索接口也一样),歌词接口需要 media-user-token(订阅态)才能拿到;
// 本实现保持上游行为:拿不到就返回 { lyric: '', tlyric: '' },不抛错。
// 统一接口约定:{ promise, cancelHttp };promise resolve → { lyric, tlyric }
