GoogleChromeLabs/ndb ? reverse-engineered prompt

Build me a Node.js debugger that feels like Chrome DevTools, but tailored for running and fixing Node apps. I want to be able to start it from the command line, point it at a server file or an npm script, and have it open a nice debugging UI where I can set breakpoints, step through code, inspect variables, use the console, and see async stacks.

It should also handle child processes automatically, let me pause before modules are loaded, and make it easy to edit files directly in the UI and save changes back to disk. I’d like it to keep my focus on my own code, so it should hide most Node internals and other noise by default. If possible, include a simple way to restart the last run and support profiling when I launch with a profiling flag.

Use the current docs online if you need to, and make it feel polished and ready to use.
