组件拆分过细 导致无法定制开发

现在架构 组件有以下问题 导致无法定制开发：

1. 打包工具捆绑了 build-script + webpack ，无法切换到 rsbuild 等工具
2. 因为要拆包，所以内部大量组件使用 externals 形式注入 react，且版本使用16 较低
3. 物料包大量资源指向 cdn，不支持内网部署
4. 物料以url加载为主，不支持本地物料

小项目的使用者，期望能够以单体项目直接加载本地物料的方式，打包和部署一个低搭界面

The issue names no files, tests, or entry points. Start by mapping the packaging and material-loading architecture, then identify how webpack, React externals, CDN URLs, and local materials are wired together. Done would require a defined, tested path for a monolithic project to use local materials, avoid CDN deployment, and support an alternative bundler.
