mahmoud-yousefi/contacts-manager-app ? reverse-engineered prompt

Build me a simple contacts manager app where I can keep a list of people and their contact details in one place.

I want a clean React interface that lets me add a contact, edit it, delete it, and browse through the saved contacts easily. Include basic fields like name, phone number, email, and maybe notes or company if it makes sense. It should be easy to search or filter contacts so I can find someone fast.

If this project already has a small server setup, wire the app up so the contacts are saved and loaded instead of disappearing on refresh. Make the experience feel polished and straightforward, with a responsive layout that works on desktop and mobile. Keep the code organized and make sure it runs with the usual create react app workflow. If you need to look up current docs online for anything, go ahead.
