2dust/v2rayN ? reverse-engineered prompt

I need a desktop GUI client for managing different types of proxy connections. It should work on Windows, macOS, and Linux. The main purpose is to have one simple app to handle protocols like V2Ray, Xray, Shadowsocks, and Trojan, basically all the common ones. I want to be able to import server configurations from my clipboard or from a subscription URL, see them in a list, and then just click to activate a connection.

The app should be the central hub for all my proxy servers. The interface should be really straightforward: a list of servers, a connect/disconnect button, and an icon in the system tray to show the connection status. Please build this using C# and a modern cross-platform framework so it feels native on each OS. It should also be able to configure the system proxy settings automatically when a server is activated.
