 - 优化 RAG 检索，支持根据文件 pattern 来检索（Agentic Mode）
 - 重构智能体对于“工具变更/模型变更”的处理逻辑，无需导入更复杂的中间件
 - 重构知识库的 Agentic 配置逻辑，与 Tools 解耦
-- 新增Sqlite Web UI 方便通过Web页面管理数据库中数据[#463](https://github.com/xerrors/Yuxi-Know/pull/463)
 - 将工具与知识库解耦，在 context 中就完成解耦，虽然最终都是在 Agent 中的 get_tools 中获取
 - 优化chunk逻辑，移除 QA 分割，集成到普通分块中，并优化可视化逻辑
 - 重构知识库处理逻辑，分为 上传—解析—入库 三个阶段
