sumankayal247/my-butler ? reverse-engineered prompt

Build me a small Linux desktop butler app that sits in the bottom left corner of the screen and stays there across workspaces. It should feel like a tiny sticky widget, not a normal app window, so it does not show up in the taskbar, Activities overview, or Alt Tab. I want a text box where I can type simple commands like open firefox or ask it to do a task, and when I submit it, the butler reacts with a changing pose and speech bubble while it works.

Please make it run on Ubuntu or GNOME with Python 3 and PyQt6, and use the needed window manager tools so it behaves like a real desktop overlay on X11 or XWayland. Include an easy way to launch it, plus a startup script so it can run automatically when I log in. If you need to check current docs for any desktop behavior quirks, go ahead and look them up online.
