Build me a simple MERN todo app that lets me add, view, edit, and delete tasks. I want a clean React front end, a Node and Express backend, and MongoDB for storing the todos so the list stays saved after refresh.

Make it feel like a basic starter project that actually works end to end. Include a simple form to create a task, a list to show all tasks, and basic controls for updating and removing items. Use the existing setup in the repo and wire up the server and client so I can run the whole thing with one command.

Please make sure the app handles the database connection properly with an environment variable, and set it up so it is easy to run locally. If you need to check current best practices or docs online, go ahead and do that.
