feat(review): 核对包改成医生读得懂；资料库超声一路只留给 agent 的参数

- ceus：灌注指标改为对病灶去暗区（roi_perf）和紫圈（roi_pan）两组算，roi_all 指标删除；
  D1–D4 仍要 roi_all、roi_perf 两条都过才定位（负责人 2026-10-17：医生要正常区与病灶对比看）
- build/library：tic.json 只出两组 11 个指标与 7 个槽位的视频时间；医生截图挪进
  ultrasound/keyframes/key.png，UltrasoundRoute 去掉 key_image、keyframes 多一个 key
- review：TIC参数.csv 取代 TIC结果.csv；问题清单按原因对照表写成大白话，对照表外的原因报错；
  程序原文进 snapshot/问题清单_原文.csv；说明.pdf 整份重写为合作者口吻
- 文档：结构.md、医生核对包、装配两个库、CEUS定量

任务书 04。
