总工andmultica-agent e6f761f8c8 feat(workflows): 五类用途识别与导入确认闭环 (HEL-636)
- 判型器 classify_usage:按输出节点(sink 检测)与被消费图片槽判定
  文生图/图生图/文生视频/图生视频/参考图生视频,不依赖文件名/模型名/
  固定节点 ID;歧义(单散装图+视频、同图双输出)与无输出给中文说明
- 参考图组泛化:任意 <group>.<prefix>N 连续编号且均接图源的输入成组
  (MiniMaxH3 特判仅剩标签美化);patcher 支持通用组回填
- workflows 表新增 usage/usage_source,幂等迁移回填;判不出的存量行
  停用待确认;kind 语义收窄为输出媒体,历史无损
- 导入改两步向导:分析→预览(判定依据/输出节点/媒体槽角色可改/
  参数预览/警告)→确认保存;usage_source=user 的纠正不被重分析覆盖
- 生成页按 usage 过滤;待确认工作流不进生成页且提交被拒
- 新增 test_usage_classifier / test_workflow_import_confirm;
  两个旧测试夹具补输出节点以匹配新守卫

"""HEL-636 A1–A6: the five-usage classifier judges from graph evidence only.
Every case feeds real (or minimally mutated) ComfyUI API exports — never a
file name, model name or fixed node id — and asserts the usage, the media
