oxidezap/client ? reverse-engineered prompt

Build me an unofficial WhatsApp client in Rust that feels like a real app, not a toy.

I want a desktop window plus a background daemon so the session stays alive even if I close and reopen the UI. It should let me pair my account, see chats with saved history, search messages, send text and media, and handle 1 to 1 voice and video calls. I’d also like a browser based version that can either run on its own or connect to the local daemon on my machine.

If it fits naturally, include a simple command line way to talk to the same account too. Keep the app polished enough for Linux, macOS, Windows, and the web, and make the local setup straightforward. If you need to check current Rust or web build docs along the way, go ahead and look them up.
