VLM对hair/skin_tone/face_shape/outfit四项输出"无法判断"导致Seedream自由发挥， 发型服装还原失败。双层修复： 1. prompts.py image_analysis system prompt强化： - 明确has_person=true时hair/skin_tone/face_shape/outfit四项禁止填"无法判断" - 提供hair/skin_tone/face_shape/outfit的具体示例值供参照 - 即使局部遮挡也要基于可见部分合理推断 2. worker _xml_to_product双层保险： - VLM仍输出"无法判断"时，用通用兜底值（自然发型/自然肤色/标准脸型/日常服装） - 保证portrait_prompt始终包含完整外貌描述（性别/年龄/发型/肤色/脸型/穿着/表情） - 确保preheat_trust_chain的人物描述过滤器(len>=10)不会过滤掉结果 预期：人像图VLM输出具体外貌→Seedream t2i还原发型服装脸型→ Seedance reference_image为高还原度AI人像→人物整体相似度>85%（上次脸部80-90%，本次服装发型也应还原） |
