fix(organize): 入库二级分类对齐MoviePilot结构 + 手动整理不再作为一级目录

- anime 顶层目录独立为「动漫」(动漫/{国漫,日番,儿童}),不再混入电视剧
- categoryPhysicalRootDir 把二级分类名映射到正确顶层:
  动画电影/华语电影/外语电影→电影; 国漫/日番/儿童→动漫;
  国产剧/日韩剧/欧美剧/纪录片/综艺/未分类→电视剧; 成人→成人
- 新增 staging 重定向:目标根落在「手动整理」等暂存目录时,上提到
  父级媒体根,媒体真正归入分类目录(如 媒体/电影/华语电影/片名),
  而非停留在手动整理下或与分类目录并列
- organizeLibraryRootForLayout 跳过 staging 名的库,避免回流暂存目录
- 同步更新陈旧测试期望(电视剧→动漫)+新增 staging 重定向测试
