lazyfetch/runtime ? reverse-engineered prompt

Build me a full stack web app called Runtime where people can sign up, log in, and write code in the browser, then run it on a remote server and see the output right away.

I want a clean dashboard with saved projects, a Monaco style code editor, language selection for Java, Python, C, C++, and JavaScript, and a panel that shows recent runs and submission history. It should support both quick run requests and an interactive terminal mode where the user can type input live and see stdin and stdout stream back in real time.

Please make it feel polished and modern, with auto save for projects, keyboard shortcuts like Ctrl Enter to run, and a simple login flow including email and password plus Google login. Use safe isolated execution for user code, with queued jobs so runs do not block each other, and store user data, projects, and results properly. If you need to check current setup details while building, look up the latest docs online.
