feat: SearXNG 搜索集成 + DevTools Docker + PG 备份 + 文档更新

Browse Source 
- web_search 工具/插件接入自托管 SearXNG，支持百度/必应/搜狗/360搜索
- DevTools 加入 docker-compose.dev.yml，devtools/Dockerfile
- scripts/pg-backup.sh 数据库备份恢复脚本，docs/pg-backup-migration.md
- 后台思考 + datetime 插件时区默认 Asia/Shanghai
- docker-compose 对齐 volume 名称，清理 tool-engine 残留引用
- README.md / Deploy.md 更新至当前架构（移除简报/tool-engine，新增搜索/跨端同步/DevTools）
