iomgaa c582fe426f feat(build): 任务书 02 第四阶段代码——build 装入 CEUS 结果
- build.yaml 加必填字段 ceus_run(CEUS 运行目录或 null)。
- 不为 null 时按视频号找结果;在 failed.csv 里或缺结果目录的整例跳过,记 C15;关键帧图沿用 C14 检查。
- 资料库超声一路加 keyframes/<槽位>.png(去附加数据重编码)和 tic.json(白名单逐字段构造:
  四条曲线的拟合成败与 R²、灌注指标、紫圈曲线是否可用、7 个槽位的定位与视频时间或原因)。
- manifest 的 CEUS 来源写运行号;泄露扫描已覆盖 tic.json,补命中测试。
- 真实构建等配准改完、全量 CEUS 运行之后再做。

"""build 装入 CEUS 结果:C15 跳过、tic.json 只有白名单字段、关键帧去附加数据、运行目录不合规时停下。
预期的 tic.json 键集合照任务书 02 第四阶段的文字手写:四条曲线各自拟合是否成功和拟合优度(R²);
病灶两条曲线的灌注指标(同旧 replay summary 的 perfusion_metrics 段);紫圈曲线是否可用;
7 个槽位各自是否定位到、定位到的视频时间、未定位的原因。
