- 后端新增远程库→本地结构映射（emby_remote_web.go）：Library/Media/SeriesCard 与本地完全同构，前端无感知 - /api/libraries（含 with_preview）、/api/libraries/:id、/api/libraries/:id/media、 /api/libraries/:id/series、/api/libraries/:id/series/episodes、/api/media/:id、 /api/media/:id/episodes 全部支持远程伪装 ID 透传映射 - /api/stream/:id 对远程条目 302 直连远程 Emby 原地址（播放不经过本机） - 库内容按 CollectionType 过滤（电影库取 Movie、剧集库取 Series）， RecursiveItemCount 作为系列集数；修复伪装 ID 双重编码导致的图片/详情 500 - SPA fallback 放行 /library/embyremote~ 前缀（不再被当作 Emby API 路由 404） - 前端：远程库/条目标记 is_remote_emby，隐藏扫描/刮削/编辑/NFO/回收站/ HLS 转码等不适用操作；后台管理面板过滤远程库
