vivekpanchal-mv/MERN-_TODO ? reverse-engineered prompt

Build me a simple full stack todo app where I can add, edit, delete, and mark tasks as done.

I want each task to have a title, a priority like low, medium, or high, and an optional due date. If a task is overdue, make it stand out clearly. Let me filter the list by all tasks, only todo items, or only completed ones, and give me a way to clear all finished tasks at once. It should also support renaming a task by double clicking the title or using an Edit action.

Make it a MERN app with a React front end and a Node, Express, and MongoDB backend, and keep the setup simple so I can run the client and server locally. Dark mode should follow the system setting automatically. If you need to check current docs or best practices while building it, go ahead and look them up online.
