Build me a lightweight native Discord client for Linux and Windows that feels fast and uses very little RAM, with no Electron and a fully theme driven interface. I want the whole app to be controlled by editable theme files, so I can switch looks without changing the binary, and have changes reload as soon as I save them.

It should connect to real Discord, support chat, direct messages, replies, reactions, editing and deleting messages, message selection and copy, keyboard shortcuts, and a simple command palette for jumping around. It should also handle voice calls with mic and speaker selection, mute and deafen, live levels, and decent audio quality.

Please make it keep working in the tray, remember panel sizes, and include a few built in themes plus a demo mode when no token is set. If you need current docs for Discord or the libraries, look them up online first.
