feat(python): 完成 Python 全量迁移——剩余平台、登录通道与公共层修复
- 新增 5sing/apple/xm/me/qt/lr 平台包与取流实现（含 xm-sign、MissEvan 签名、蜻蜓 HMAC、Apple developer token） - 新增 wy/kg/tx/lr 登录：扫码、手机号、账密（kg 20028 风控指纹）、cookie 绑定、kg/tx 续期 - request 层：保留多值 Set-Cookie；JSON body 紧凑化（修复 kg 网关验签）；直连不经系统代理（对齐 Node） - 登录路由统一 Body(embed=True)，修复扫码轮询 422；lifespan 接入登录续期调度 - ruff/format/pyright 全绿；14 平台真实联网与 HTTP 路由验证通过

"""QQ音乐链接解析（移植自 sdk/tx/parse.ts）。
|
||||
|
||||
歌曲链接形态：
|
||||
* https://y.qq.com/n/ryqq/songDetail/<songmid>
|
||||
* https://y.qq.com/n/yqq/song/<songmid>.html
|
||||
* https://i.y.qq.com/v8/playsong.html?songid=<数字 id>（先反查 songmid）
|
||||
* ...?songmid=<songmid>
|
||||
|
||||
元数据走 fcg_play_single_song（顺带拿 file 体积信息）。直链 url/type 是尽力附带：
|
||||
取流失败只返回元数据，不影响解析结果（与上游一致，VIP/下架曲目即如此）。
