This automates the tedious process of adding new languages to Next.js apps using next-intl. It handles the complete workflow: duplicates your English translations to create the new language JSON file, updates the routing configuration in both routing.ts and middleware.ts, and modifies your language toggle component to include the new option. Saves you from manually tracking down all the scattered config files and ensures you don't miss any steps. Most useful when you're scaling from a single language to multiple locales and want to avoid the inevitable "why isn't my new language showing up" debugging session.
