feat(scrape): 覆盖方式加「更新」并设为缺省,季集缺元数据不写占位,作品类型判定统一

- 每次写入在 scrape_record.files[].hash 记 sha256;update 模式只覆盖本工具写过且没被改过的文件,
  被改过的跳过(scrape_user_modified),内容没变不重写(scrape_unchanged),旧记录无 hash 按修改时间兜底;
  迁移 0070 给 scrape_record.mode 加 update,设置缺省改为 update(旧值照旧有效)
- 季 / 集单元缺元数据时按 TMDB id 现取季详情补齐;仍缺跳过(scrape_metadata_missing)并记 partial,不写占位 NFO
- scrapeKindOf 统一作品类型判定,合集 / 其他类作品 NFO 根元素为 <movie>;TMDB 映射按作品类型过滤 entity_type
- 兜底异常记 scrape_internal_error 并保留已写文件结果
- 新增 scheduleEntityRescrape(刮削过的作品延后排 update 重刮,排队记录合批防抖)
