ef5d8c8d41 feat(media): scan every folder level, save incrementally, TV tags, seed task progress (#3263)
* feat(media): scan every folder level, save incrementally, TV tags, seed task progress

Media library
- Merge mode now walks every folder level instead of only the first one.
  A folder that directly contains media files is one collection and is not
  split further; a folder without media is descended into. Loose files in
  the scan root stay individual items. Depth is capped at 16.
- Scanning no longer buffers the whole tree before writing: items are
  flushed to the database every 20 items or 3 seconds, for all four media
  types, so results appear while the scan is still running. Skipped and
  failed items still advance the progress counter.
- The scan path type tag now decides movie vs. series. Tags such as
  TV series / anime / variety / documentary mark every video under the
  path as "tv" (shown as series in Emby, also for single files); movie
  tags force "movie" even when merge mode is on. Unrecognised tags keep
  the old rule (folder items are series). Emby virtual folders use the
  same rule.
- Fix: a music folder containing a non-audio file was dropped entirely.

Playback URL
- When no site_url is configured and the request host is a loopback
  address (127.0.0.1 / localhost / ::1), stream_url now returns relative
  /d and /p paths instead of absolute loopback URLs. An explicit site_url
  or a forwarded host still produces absolute URLs.

Seed tasks
- Seed generation reports progress by bytes hashed plus a stage message
  and is exposed at /task/seed_generate.
- Seed save, rapid upload and transit transfer register a display-only
  task at /task/seed_save (the operation stays synchronous) so progress
  is visible in the task list.

Tests cover tag classification, index-length checks, level-by-level merge
scanning (stop at collection, list errors, depth limit) and loopback
detection.

* fix(server): keep site_url path prefix in playback base url

site_url 允许配置成 /openlist 这样的路径前缀;原先只有以 http 开头才走绝对地址,前缀模式下播放地址会丢掉前缀导致 404。改为配置了 site_url 就统一用 GetApiUrlFromRequest 生成。

* feat(media): season-aware episodes, album admin api, cover upload, zip export

- 扫描:季目录(第N季/Season N/S01)解析季号写入 EpisodeInfo.season,Emby 与播放器可按季分组;显式电影标签不再被季目录反推成剧集;merge_depth 语义固定为「第 N 层=一条记录」,与模型注释、UI 一致
- 刮削:音乐条目的文件自带封面(data:/thumb:/站内地址)不再被在线封面覆盖
- 后台新增:封面 URL/上传(/admin/media/items/cover)、专辑聚合列表与批量编辑(/admin/media/albums、/album/items、/album/update)、条目可编辑字段扩充(选集/视频类型/季集/时长/外部ID)
- 导入导出升级为 zip(media_export.json + covers/),导入兼容旧 JSON
- Emby:多季合集按每集 season 拆分 Season,集 ID 带季号避免跨季重号
- fix(seed):中转转存部分文件失败时任务按失败收尾,不再一律标记成功

* fix(media): patch semantics for item update, transactional album update, concurrent cover export

- UpdateMediaItemAdmin 改为 PATCH 语义(字段全部指针,只写出现过的键),修复只传 hidden 也会清空 cover/plot 的问题;cover 增加 12MB 上限
- 专辑批量更新走单事务(新增 db.UpdateMediaItems),失败整批回滚;旧封面文件在事务成功后才删除
- 导出封面改为并发读取(4 并发,单张 8MB / 总量 512MB / 5000 张上限),避免大库导出逐张串行

* fix(media,seed): unify episode ids, season fallback, cancellable seed tasks, periodic flush

- Emby 集 ID 统一走 parseEpisodeID(新格式 ep-item-season-num,兼容旧两段),修掉封面/刷新/续播列表里仍假设旧格式的三处;续播能唯一定位时补季号
- 季号兜底 seasonFromText 与前端 episodeSeasonOf 规则对齐,老数据不会在 Emby 和网页端分到不同季
- 种子任务真正可取消:任务 ctx 重新绑定(tache Add 会覆盖)、保存 IO 改用任务 ctx、逐文件与哈希读取检查取消、取消后状态为 Canceled
- mediaSaver 增加定时落盘协程,Close 时停表并收尾 Flush

* feat(media): artist aggregation api and image exif lookup

- 新增 GET /fs/media/artists(db.ListArtists):按 album_artist 聚合专辑数/曲目数/封面,供音乐库「按艺术家」分类
- /fs/media/albums 支持 album_artist 过滤,艺术家下钻时只取该艺术家的专辑
- 新增 GET /fs/media/exif:按需读取图片文件头解析 EXIF(设备/镜头/曝光/焦距/时间/GPS)并缓存,解析失败返回 available=false 而不是 500

* fix(emby): return full UserDto from /Users/Public (issue #3301)

严格类型的客户端会把 user['Policy'] / user['Configuration'] 直接强转成 Map,
之前 /Users/Public 只返回 5 个标量字段,转 null 时抛异常并中断渲染(封面全挂)。

- 删除 embyPublicUserDto,/Users/Public 直接复用 embyUserDtoOf,与登录接口结构一致
- 新增 embyUserConfiguration(),按官方 UserConfiguration 给全默认值(空 map 同样是缺键)
- 补 TestEmbyUserDtoHasPolicyAndConfiguration 回归测试

* feat(media): pure-go pdf cover rendering, keep existing cover by default, same-dir thumbnails

- PDF 封面改用纯 Go 光栅化(github.com/go-pdfkit/render,BSD-3、无 cgo):渲染第 1 页再缩到 300px,矢量/扫描件/Flate 压缩图都能出图;失败时仍退回原来的内嵌 JPEG 扫描。渲染带 MaxPixels/MaxDuration 上限,防止恶意或超大页面拖住扫描
- 新增设置 media_overwrite_cover(默认关闭):刮削不再覆盖条目已有封面,只负责补空;需要替换时手动打开。原先只对音乐做了保护,现在统一到所有媒体类型
- 缩略图存储新增 samedir 模式:封面写到媒体文件同目录,文件名为「原文件名.图片后缀」(song.flac.jpg),不覆盖原文件,也不需要配置 VFS 目录
- 依赖代价:go 指令 1.26.0 -> 1.26.4,新增 render 及其纯 Go 依赖(go-gfx/opentype 等),go.sum 由 tidy 收敛

* feat(media): add skip-file-metadata switch (default off)

- 新设置 media_skip_file_metadata(默认关闭):开启后扫描与刮削都不读取媒体文件内容
- 音乐:扫描与刮削均跳过 ID3/Vorbis 解析,退回目录名/文件名,内嵌封面与内嵌歌词一并跳过
- 书籍:刮削时跳过 EPUB/PDF 内嵌封面提取
- 图片:刮削时跳过 EXIF(拍摄时间/地点/设备),缩略图仍生成
- 书籍封面依旧只在刮削阶段提取,扫描阶段完全不读文件

* feat(seed): support folder expansion, split mode and structure-preserving paths

- 右键目录也能生成种子:后端递归展开目录下所有文件(深度/数量上限,逐目录校验权限)
- 新增 preserve_structure(默认关闭):开启后种子内保留相对目录结构,关闭时拍平成文件名,重名自动加序号
- 新增 split(默认关闭):每个文件生成一个种子;关闭时全部合并(默认)
- 默认命名:单文件/单目录用其名字;多选合并固定为 torrent
- 能力探测接口同步支持目录,前端按展开后的文件列表展示哈希/流量
- 单测覆盖命名规则、保留/拍平路径与重名处理

* feat(seed): compute missing hashes from source files when converting

- ConvertSeed 新增 compute_missing / file_base_path:缺哈希时按种子内相对路径读取源目录文件补算,而不是直接返回不可转换
- torrent 目标按整包拼接计算 SHA-1 pieces(解决 piece boundary crosses the next file),CAS 目标按 10 MiB 分片补 MD5
- 补算后仍不满足时返回 400 并带具体原因,避免前端误判成功

* feat(seed): persist overall comment when converting

- /fs/seed/convert 新增 comment 字段(指针,允许清空)
- 转换与保存注释合并为一次请求,前端不必先保存再转换

* feat(seed): convert to multiple target formats in one request

- /fs/seed/convert 新增 formats 数组(去重、bt 别名、最多 3 个),逐个编码并写入目标目录,返回 artifacts
- 每个目标独立解码,避免 CAS 补算修改 PieceSize 后污染 torrent pieces
- 预检仍保留「不可转换 + 原因」的响应;单目标响应字段保持兼容
- 新增 TestSeedConvertTargets

* fix(seed): identity conversion is always feasible and folder roots no longer nest twice

- seedConversionStates 现在接收源格式:目标等于源格式时直接可行,不再用「按文件 pieces」去诊断整包结构。合法 torrent(pieces 跨文件)之前被误报 piece boundary crosses the next file,导致预览页对当前格式打叉\n- ConvertSeed 对同一格式直接复制原始字节,跳过诊断与重新编码\n- 保留目录结构时,只选一个目录以该目录为根,修复「剧/剧/S01/...」重复嵌套\n- 新增回归测试:身份转换可行、跨格式仍诊断、单目录/多目录保留结构路径

* fix(seed): keep the torrent's global pieces so it can be re-encoded

- Seed 新增运行时字段 GlobalPieces:解析 .torrent 时保留整包 SHA-1 pieces(含 x-openlist 种子),重新编码直接复用,不再按文件拼接\n- DiagnoseConversion 在存在整包 pieces 时跳过「piece 跨文件」检查;否则合法 torrent 会被判成不可转换(Cannot convert to torrent: piece boundary crosses the next file)\n- TorrentFromSeed 优先使用整包 pieces,并对无效哈希返回诊断而不是静默拼接\n- 移除文件 / 重算哈希后清空 GlobalPieces,避免用对不上的旧 pieces 编码\n- 新增往返测试:跨文件 pieces 编码→解析→再编码字节一致;逐文件 pieces 仍拒绝跨文件拼接

* fix(seed): expose seed-level hash availability for torrents

BT 的 pieces 是整包的,跨文件时无法拆到单个文件(ValidateSeed 要求每文件片数 = ceil(size/piece)),此前这些文件拿不到 pieces,前端按文件判断就全显示 needs file;现在 SeedFromTorrent 汇总 available_hashes / available_piece_hashes,前端优先按种子级标记显示,并补生成到解析的往返测试

* fix(seed): accept single-file torrent name differing from x-openlist

单文件 torrent 的 info.name 是文件名(带扩展名),x-openlist 的 seed.name 可以不带扩展名;一致性校验此前直接比较两者,判定种子损坏,导致解析 400、前端兜底本地解析(无 conversions/无哈希,全部显示 needs file)。现在单文件允许 info.name == base(seed.Files[0].Path),并补回归测试

* fix(media-seed): address audit findings and review feedback

- Enforce seed source visibility, bounded hashing, and stream cleanup.

- Apply conversion selections and hash matrices, preserve comments and global pieces, and restore legacy episode IDs.

- Correct task cancellation and retries, scan persistence, and cover protection.

- Bound and validate media ZIP import/export, authorize public aggregates, and handle cover edit patches.

- Add regression tests and extend the CI test scope.
