📝 Walkthrough

Walkthrough

This PR updates the Rspack/NestJS example project to modernize its development tooling and HMR integration. The dev script now uses cross-env to explicitly set NODE_ENV to development and runs rspack in watch mode. The Rspack configuration is refactored to derive a centralized isDev constant that controls both entry point selection and plugin configuration. The application's hot module replacement is migrated from CommonJS module.hot to ESM import.meta.webpackHot. TypeScript configuration files are added to define compiler options and build-specific exclusions.
