Build me a desktop AI companion app that lives on the screen as a small floating mascot, always on top, with a playful anime inspired vibe like Amadeus from Steins;Gate 0.

I want it to let me chat normally, talk to it with voice, and hear responses spoken back. It should remember past conversations and facts about me, detect emotions, and show those emotions in the avatar and chat. Make it work as a compact mascot mode first, where the character can float around the desktop, be dragged, and show replies in a speech bubble. Clicking it should expand into a full chat panel with history, voice call mode, reminders, and settings.

Please include a simple settings screen so I can choose the AI provider, model, voice, and character without editing files. Make it feel like a real desktop app with a tray icon and a shortcut to hide or show it. If anything needs current setup details, look up the latest docs online and wire it up cleanly.
