feat(datasets): YOLO 风格标注数据集与几何/像素增强

- yolo: images/ 与同层 labels/ 的路径约定、`class_id cx cy w h` 归一化行解析
  （兼容分割多边形取外接矩形）、data.yaml 读写；缺失或空 txt 即无缺陷样本
- film_defect: 抛出图像、框、图像级标签；label_mode 决定多热向量还是互斥下标
- transforms: 图框同步的 Resize / Letterbox / CenterCrop / RandomResizedCrop /
  翻转 / ColorJitter / GaussianBlur / PerImageStandardize
- target_encoder: 高斯半径与 heatmap / wh / offset / mask 监督信号编码
