feat(ceus): 两半坐标换算改为每段视频配准，加目视核对脚本
- 第 1 步分屏后在两半扇形区内用边缘图归一化互相关估 (dx, dy)，再用逐帧多块模板匹配的中位数独立核对； 两者各分量之差超过门槛（15 像素）这一例第 1 步失败。删掉「两个视图左上角相减」的实现与测试。 - 门槛依据：34 例中走完第 1 步的 29 例，差值中位 2、95 分位 6.2、最大 13；参数与门槛在同一批视频上调出。 - scripts/ceus_align_review.py：只做第 1 步，出扇形区棋盘图与边缘叠加图，混入错开 15–30 像素的 阴性对照、随机编号；计分时任一对照未被判「没对齐」即作废。 - ceus_quant 读 review.csv：不通过的病例第 1 步失败；表里没有这段视频或平移对不上即停。 - 配准与紫圈颜色参数进分割缓存键。 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

"""配准的目视核对（任务书 02 第三阶段）：`render --config <ceus.yaml>` 出图，`score --run-dir`

计分。
|

|

render 只做第 1 步、不用显卡：第 1 步成功的每例出棋盘拼图和边缘叠加图（只截扇形区），另随机挑
|
||||
`align_check` 段定的例数把配准故意错开当阴性对照；图按打乱的编号放进 `images/`，对应关系写
|
||||
`key.csv`（不给判读者）。score 对照 `verdicts_a.csv`、`verdicts_b.csv`：任一张对照被任一人判成
|

「对齐」或「看不清」就作废（不写 review.csv，退出码 1）；否则写 `review.csv`，两人都判「对齐」才
|

通过。终端只打印计数。
