Add desktop integration and Arch PKGBUILD

- steam-dice.svg: flat dice icon on Steam-blue gradient
- steam-dice.desktop: launcher entry under Game category
- PKGBUILD: steam-dice-git, builds from GitHub source
- Use setDesktopFileName for correct Wayland WM_CLASS, with
  local SVG fallback when running from the source tree
