xslandClaude Opus 4.8 94ad95850e feat(接口2): 新增生发后图片(ComfyUI/Flux inpaint)
在发际线预览基础上,每种发际线再出一张「植发3个月」生发图:

- hairline/mask.py: headmark 5步法遮罩(额头上部区域∩SegFormer头部=ROI,
  取发际线曲线以上闭合区域);用 hairline_texture_black 渲染黑线替代手绘检测;
  compose_comfy_rgba 合成 RGBA(alpha=255-mask, 透明=重绘区, 对齐 ComfyUI mask=1-alpha)
- hairline/comfyui.py: ComfyUI 客户端(默认8182),/upload/image+/prompt(改节点26+随机seed)
  +轮询/history+/view 取回生发图
- hairline/render.py: 抽出 build_overlay_layer 供遮罩取曲线像素
- hairline/service.py: extract_context 一次出 landmarks/parse_map/502点;
  generate_grow_results 每种=预览+生发图(同步串行N张,单张ComfyUI失败则grown置空不拖垮整请求)
- app.py: /hair/grow 返回 results[].grown_image_base64;重活放线程池避免卡事件循环
- add_hair.json 工作流 + hairline_texture_black/ 黑贴图入库
- 测试: test_mask.py(遮罩几何) + test_api mock ComfyUI 验 grown 字段,35 全绿

实测(5090): female 5张生发图同步约18s;预览/生发图人物五官服饰背景保持、黑线已清除。
