feat(react19-migration): 阶段1 - 项目基础设施重建

- T1.1: 卸载 Vue 依赖，安装 React 19 + Ant Design 5 + Zustand 5 + AntV 全家桶
- T1.2: Vite 配置迁移 (plugin-vue → plugin-react, manualChunks 更新)
- T1.3: TypeScript 配置迁移 (jsx: preserve → react-jsx, 移除 .vue)
- T1.4: ESLint 配置迁移 (Vue 规则 → React/Hooks/Refresh 规则)
- T1.5: 入口文件迁移 (main.ts → main.tsx, App.vue → App.tsx, div#app → div#root)

验证: npm run dev 成功启动空白 React 应用
