🚀 快速开始:
1. 首次使用建议先运行"创建演示对话场景"
2. 如有PDF世界观文档，选择"处理PDF世界观文档"
3. 通过"启动双AI对话系统"开始角色对话

📁 文档格式说明:
- 世界观文档: worldview_template_coc.json (参考COC设定)
- 角色设定: character_template_*.json (包含详细人设)

🔧 系统功能:
- PDF自动转换为RAG知识库
- 基于向量相似度的上下文检索
- 持久化对话历史存储
- 角色设定一致性保持

📝 自定义角色:
1. 参考 character_template_*.json 格式
2. 保存到 knowledge_base/ 目录
3. 重启对话系统加载新角色

💾 对话数据:
- 历史对话保存在 conversation_data/ 目录
- 支持会话恢复和历史查看
- 自动记录使用的上下文信息

⚠️  注意事项:
- 确保模型路径正确设置
- 首次运行需要下载向量化模型
- PDF处理需要足够内存
