feat(scrape): 任意目录就地刮削,按路径识别作品,每次刮削一条记录(SCR-2)
- POST /files/scrape 改为对目录 / 视频文件刮削:已登记用作品,否则按路径识别(本地 + TMDB), 认不准返回候选,选定后再提交;未登记直接用 TMDB 字段,addToLibrary 顺手建作品 - 作品详情重新刮削、入库后自动刮削改为对作品目录刮削,同一实现 - 迁移 0058_scrape_record 替代 media_scrape;GET /files/scrape-records - 与 MP ScrapingChain 的文件布局差分(7 个场景,3 处登记偏离) Co-Authored-By: Claude Opus 5.5 <[email protected]>
