refactor(api)!: 平台 id 回退——joox/5sing/bili/apple 恢复全名，目录对齐 bd/mg
- 撤销 3381e9b/1b972ec 中 jx/5s/bl/ap 四个短码，恢复 joox/5sing/bili/apple； qian→bd、migu→mg 保留 - 目录与文件对齐保留的新 id：sdk/qian/→sdk/bd/、sdk/migu/→sdk/mg/、 sdk/apis/qian.ts→bd.ts、migu.ts→mg.ts、src/http/migu-stream.ts→mg-stream.ts （规则改为「目录=对外 id」，聚合入口的模块变量同步更名；music.migu.cn 等域名、 上游 music-lib 对照注释、miguGet 等功能标识符不动） - 对外 id 全表：kw kg tx wy qs xm me qt lr mg bd joox 5sing bili apple **破坏性变更**：joox/5sing/bili/apple 四平台的 URL、/sources 返回与 data/auth.json 凭据键恢复全名，已存短码键的登录态需重新登录。 验证：typecheck ✓、pnpm test 112/112 ✓
