Version: 0.9.15.dev.260412

后端：
1. 排程工具从 tools/ 根目录拆分为 tools/schedule 独立子包
- 12 个排程工具文件等价迁入 tools/schedule/，tools/ 根目录仅保留 registry.go 作为统一注册入口
- 所有依赖方（conv / model / node / prompt / service）import 统一切到 schedule 子包
2. Web 搜索工具链落地（tools/web 子包）
- 新增 web_search（结构化检索）与 web_fetch（正文抓取）两个读工具，支持博查 API / mock 降级
- 启动流程按配置选择 provider，未识别类型自动降级为 mock，不阻断主流程
- 执行提示补齐 web 工具使用约束与返回值示例
- config.example.yaml 补齐 websearch 配置段
前端：无
仓库：无
