Melodify

Added:

• Proper error messages that actually tell you what went wrong
• Auto-retry when requests fail with smart backoff delays
• Offline mode that detects when you lose connection and tries to reconnect
• Circuit breaker to stop hammering endpoints that are down
• Disk cache for album art so it doesn't redownload everything
• Status messages in the HUD when stuff goes wrong
• Settings to customize which modifiers you want on keybinds

Optimized:

• Album art cache caps at 20 images in memory (was unlimited before)
• Album art loads from disk first, only downloads if not cached
• Connection status properly tracked (online/offline/reconnecting/rate limited)
• Shows last known track info when offline instead of nothing
• Album art cache is thread-safe now

Fixed:

• Album art cache eating all your RAM
• Textures leaking when album art got removed from cache
• No recovery when Spotify API has issues
• No feedback when offline or rate limited
• Album art redownloading every single time
