"""猫耳FM 搜索（对应 sdk/me/musicSearch.ts，双通道聚合，与网页版对齐）。

广播剧（置顶）: https://www.missevan.com/dramaapi/search?s=&page= → info.Datas[]
  ——网页版搜索排前面的正剧来自这里；getsearch 的 type 参数只有 1UP主/2音单/3声音/4声优，没有剧集类型
声音（补足）:   https://www.missevan.com/sound/getsearch?s=&p=&type=3&page_size=&sort=2 → info.Datas[]

剧条目 songmid 用 "d:<drama_id>" 前缀（取流时自动取首个免费集，见 apis/me.py）；声音条目为裸 sound_id。
