Enhance build process and add TypeScript configuration

- Update package.json to include separate build scripts for frontend and types, and add a build server script.
- Introduce tsconfig.json for TypeScript configuration, enabling declaration files and source maps.
- Add TypeScript and Node types as development dependencies.
- Include TypeScript declaration files in the package distribution.
