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音乐评论（移植自 sdk/tx/comment.ts）。
|
||||
|
||||
两路数据源（与原文一致，接口不同、返回形状不同）：
|
||||
* 最新评论 —— c.y.qq.com 的 fcg_global_comment_h5（form 表单，cmd=8）
|
||||
* 热门评论 —— musicu.fcg 的 music.globalComment.CommentRead/GetHotCommentList
|
||||
|
||||
原文靠 `_requestObj.cancelHttp()` 做并发去重；Python 请求层没有取消句柄（见
|
||||
common/request.py 的说明），这里改用 asyncio.Task 合并同一 songmid 的并发查询。
|
||||
|
||||
两处刻意的降级/容错：
|
||||
* `middlecommentcontent` 的父评论头像与点赞数会被搬到第一条楼中楼，父条目置 null，
|
||||
随后楼中楼整体反转 —— 照抄原文，否则前端展示顺序与字段归属会和 TS 版不一致；
|
||||
* 原文 `c.replynick.substring(1)` 在 replynick 缺失时会抛 TypeError 把整页打挂，
|
||||
这里按空串处理（唯一的偏离，只影响脏数据）。
