feat(review): 医生核对包入口；CEUS 运行目录的读取收进 runs

- 新模块 review（组织层，只依赖 library、answers、runs）：把一次构建和它装入的
  CEUS 运行整理成医生可读的文件夹（CSV 带 BOM、说明与报告转 PDF、图片视频逐字节拷贝），
  入口 scripts/review_pack.py + config/review_pack.yaml。任务书 03。
- 读 CEUS 运行目录（failed.csv、结果目录、关键帧文件）从 build 挪进 runs，build 与
  review 都经它读；failed.csv 读取在边界上收严（步号须为整数、视频号不重复、列数固定）。
- library、answers 补只读函数；import-linter 增 review 契约。
- 文档：guides/医生核对包.md（过一轮硕士生阅读），结构.md 第三至八部分同步。
