klsdfernando/VoidTunnel — reverse-engineered prompt

Build me a Linux desktop app called VoidTunnel, a clean dark themed VPN and proxy client with a GUI. I want it to let me add and manage server profiles for VMess, VLESS, Trojan, Shadowsocks, and basic SSH tunneling, including importing single server links and subscription URLs. It should automatically offer to download the core networking engine on first launch, then let me connect and disconnect easily.

Please include a payload editor for HTTP header injection, system proxy setup for common Linux desktops like GNOME and KDE, real time upload and download stats, total data usage, and a live colored log view so I can see what the connection is doing. Store user settings and profiles under the normal Linux config folder.

Keep it Python based with a polished PyQt style interface, and make it runnable locally with a simple install and launch flow. If anything is unclear, check current docs online and make reasonable choices that fit the repo.
