Build me a simple remote support app for my own Windows and macOS machines.

I want a central admin dashboard that can see which devices are online, show basic status like name, IP, and last seen time, and let me send a few safe commands like open a remote terminal, view the screen, and manage files on machines I already control. It should have a clean dark interface and feel modern, with a live list of connected devices and a place to type commands and see responses.

Please make separate agents for Windows and macOS that run quietly in the background, reconnect if the network drops, and can update themselves. If you need to, look up the current docs online for the best way to build it in the latest .NET. Keep it straightforward and make sure the whole thing is easy to run from the repo.
