v1.7.4: DMG macOS con Fix Gatekeeper integrato

Macos ora viene distribuito come .dmg invece di .zip: - contiene MusicTools.app + alias Applicazioni + "Fix Gatekeeper.command" - doppio click sullo script rimuove com.apple.quarantine senza Terminal manuale -> niente piu' "App non verificata" Backend: /api/download serve .dmg con Content-Type application/x-apple-diskimage. Landing /download aggiornata con il nuovo flusso (3 step).
v1.7.3: nuova icona app + landing chiarisce limiti senza chiavi Spotify

+          <p>
+            <strong>Da Spotify</strong>: senza chiavi puoi scaricare <strong>un
+            brano alla volta</strong> incollando il link al singolo brano (l'app
+            estrae artista e titolo dai metadati pubblici di Spotify e cerca su
+            YouTube). Per <strong>album e playlist</strong> servono le chiavi API
+            — sono gratis (anche con account Spotify free) e la procedura guidata
+            nell'app ci mette 2 minuti.
