Build me a web app called ProblemForge that gives developers real world, evidence backed build this style challenges pulled from public technical discussions like Hacker News and GitHub Issues, with Reddit later if needed. I already have the Next.js and TypeScript setup, so please turn this into a polished starter app with a clean homepage, a simple way to browse generated challenge ideas, and the server side pieces needed to read from Supabase safely. Use the existing database setup and make sure the app only talks to Supabase from server code, not from the browser. If anything is missing, wire up the placeholder routes, shared components, and basic data display so the project feels like a real product instead of a shell. Keep the styling simple and modern with Tailwind, make sure linting and formatting still pass, and add whatever is needed so I can run it locally and see the app working end to end. If you need current docs, look them up online.
