Build me a small Windows desktop app that shows real time memory usage and lets me clean up system memory with one click. I want it to feel lightweight and fast, with a simple window that shows current RAM stats, a refreshable memory meter, and a clear button that can free up memory using the same kinds of system cleanup methods these tools usually use. It should run on modern Windows versions, work in both installed and portable mode, and handle admin rights properly when needed. Please make it look polished, include a tray icon or compact mode if that fits, and save basic settings so it remembers how I want it to run. If you need to check the latest Windows docs or APIs while building it, go ahead and look them up online.
