limetext/lime ? reverse-engineered prompt

Build me an open source text editor called Lime that feels like a lighter, API compatible alternative to Sublime Text.

I want a clean starting point for the project, with a working core backend and a simple frontend so I can open, edit, save, and search text files. Make it easy to add plugins later, since the big goal is to support the same kind of extension style that Sublime users expect. Keep the interface fast and minimal, with tabs, a file tree, basic keyboard shortcuts, and a command palette if that fits naturally.

Please set it up so the app is easy to run and keep improving, and include clear instructions for building it. If you need current docs or examples for anything, look them up online first. I mostly want a solid, practical foundation that can grow into a real editor, not a fancy demo.
