Deezy v0.2.8

Fixed

• Production CSP blocking covers & audio – Album cover images and audio preview playback worked in tauri dev but failed in the installed exe; the Content Security Policy was missing media-src for Deezer CDN audio URLs (https://*.dzcdn.net) and img-src was listing specific subdomains instead of the wildcard — CSP is now fully permissive for all *.dzcdn.net resources
