Icona dell'app: squircle verde con nota musicale

Creata un'icona coerente con la palette dell'app: squircle Apple-style
(corner radius ~22%), gradient verde Spotify -> verde scuro, nota
musicale (♫) bianca centrata con leggero glow, sottile highlight in
alto e bordo soft per definizione.

- assets/generate_icon.py: script PIL riproducibile, produce
  icon.png (master 1024) -> icon.iconset/ -> iconutil -> icon.icns
  (macOS) e icon.ico multi-size (Windows)
- assets/icon.png / icon.icns / icon.ico committati
- assets/icon.iconset/ in .gitignore (intermedio rigenerabile)
- build_macos.py: --icon assets/icon.icns se presente
- build_windows.py: --icon assets/icon.ico se presente
