- 新增男童/女童检测（gender_from_category 优先判童装）与童装场景图生成
（configs/kids_features.yaml：模特/场景/服装风格，同一商品固定同一组）
- 童装 SPU 字段映射：kids_type→SPU商品属性-类型、kids_age→适用年龄段、
target_audience 按性别映射、kids_type_map 女童「上衣」→「针织上衣」
- 标题生成提示词外部化：prompts/title_prompt_{1,2,3}.md + config.yaml 路由表
- 模板多站点匹配：经营站点可配多个，命中任意一个即匹配
- 种草图生成失败自动重试（seed_shot.retries，换场景/模特/风格）
- 模板导出新增 Preview 文件夹（成功产品 _composite.oss.jpg + result.xlsx）
- 修复 SKU 尺码未按从小到大排序（_size_rank 支持单一年龄码 6Y/10Y）
