- 将默认回复详细程度从"detailed"调整为"medium"，前后端保持一致 - 新增话题切换检测逻辑，当用户主动要求换话题时提供引导回复 - 优化上下文处理机制，仅在指代型追问时注入历史对话，避免模型复读旧内容 - 改进知识库检索逻辑，区分自包含问题和指代型问题的上下文需求 - 完善知识库完整性指令，确保回复详细程度与知识展开程度一致 - 重构知识库重建逻辑，支持递归扫描子目录中的文件，修复索引为空的问题 - 增强素材匹配算法，引入强信号检测机制，避免仅凭模糊匹配误发素材 - 新增素材开场白AI生成功能，支持图片、视频、文档等类型智能描述 - 改进知识库重建通知，显示具体的文件数、分片数及失败统计信息
