feat(strm): 同名多版本择优 / keep_ext，并支持合并展示与播放切换 (#30)

* feat(strm): 同名多版本择优/keep_ext，并支持合并展示与播放切换默认对同名不同扩展（如 .mkv/.mp4）按体积→mtime→扩展名优先级择优生成一条 strm，冲突打日志；开启 keep_ext 则分别生成 name.ext.strm。媒体详情与播放器可切换版本，列表继续合并同片多版本，Emby MediaSources 名称区分容器/分辨率。 Co-authored-by: truewhile <truewhile@users.noreply.github.com> * fix(meta): 边车匹配忽略 .mkv.strm 中间扩展，同片共享 NFO/海报/字幕 NFO、海报、字幕与刮削写出统一使用 mediaSidecarBase 词干，使竞女01.mkv.strm 与竞女01.mp4.strm 配对同一套竞女01.nfo / 竞女01-poster / 竞女01.srt；仍兼容历史上的 name.mkv.nfo 命名。 Co-authored-by: truewhile <truewhile@users.noreply.github.com> * fix(emby): People NFO 按共享词干匹配 keep_ext strm resolveMediaPeople 改为查找竞女01.nfo（并兼容旧的竞女01.mkv.nfo），同时修正把 decodeNFOFile 的 partial 误当 ok 导致完整 NFO 被跳过的问题。 Co-authored-by: truewhile <truewhile@users.noreply.github.com> --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: truewhile <truewhile@users.noreply.github.com>
