ujjwalanuragt/TaskManagementApp ? reverse-engineered prompt

Build me a simple task management app in this repo.

I want a clean web app where I can add tasks, edit them, delete them, mark them as done, and quickly see what is still open. It should feel easy to use on desktop and mobile, with a tidy layout and clear buttons. If the project already has some setup, please keep it working and finish the app in a sensible way instead of starting over.

Make the main screen show my tasks in a useful way, with basic organization like open and completed tasks, and a simple form for creating new ones. If it helps, use the existing project structure and look up current docs online if you need to. Please make sure it runs smoothly and the result feels like a real, usable task app.
