Dhravya/burrow ? reverse-engineered prompt

Build me a browser based dev machine that runs entirely on my own computer, inside one tab.

I want a real code editor, a terminal that feels like bash, git support, package install and remove, and the ability to run Bun scripts and see a live server preview right in the page. The workspace should save itself so I can reload and keep going, and it should feel like a normal little development environment, not a toy demo.

Please also add a local AI helper that can read files, edit code, create new files, and run commands for me, but everything should stay on device and nothing should be sent to a backend.

Make it polished enough that I can open it, type a command, start a server, and then ask the AI to make changes in the project while I watch the results update live. Use current docs online if you need to.
