Tighten the viewBox so the vinyl fills ~97% of the canvas (matching
Steam/Chrome/Papirus sizing). Add a #3968be stroke rim around the
vinyl edge so the icon remains visible on pure-black backgrounds.
Include a subtle radial inner-light from top-left for depth.
Also adds 512x512.png for Flathub compatibility.
Regenerate all PNG exports: Tauri standard sizes, Windows Store
squares, ICO, Android mipmaps, and static logos.
