NyarchLinux/NyarchAssistant ? reverse-engineered prompt

Build me a Linux desktop assistant app called Nyarch Assistant that feels like a cute AI companion, with a Live2D or LivePNG character on screen that can change expressions and switch between different characters. I want it to let me chat with multiple AI providers, use local models too, and support voice input and voice replies. It should also be able to search the web, read websites when I paste a link, answer questions from my documents, remember past conversations, and let me generate images.

Please add a small mini window mode for quick commands, a way to manage multiple chats and branch conversations, and settings for different profiles. It should also support extensions and tools so new features can be added later, including simple file access and safe command execution when I approve it. Make it feel polished and easy to use on Linux, and look up current docs online if you need to.
