"""网易云链接解析（移植自 sdk/wy/link.ts，上游 music-lib/netease/netease.go 的 parseNeteaseLink）。
|
|
|
|
支持：
|
|
歌曲 https://music.163.com/#/song?id=29732995 /song?id= / /song/29732995
|
|
专辑 https://music.163.com/#/album?id=32311 /album?id= / /album/32311
|
|
歌单 https://music.163.com/#/playlist?id=7507256008 /playlist?id= / /playlist/<id>/<n>/...
|
|
裸数字 id 由各模块自行兜底（上游 Parse 不接受裸 id）。
|
|
|
|
顺序上依次尝试原链接、path+query、hash 片段 —— 网页版把真实路径放在 # 后面，
|
|
因此必须逐候选尝试，只看 pathname 会漏掉 `#/song?id=` 这类主流形态。
