Big refactoring done using Claude. Will take some time to review later, but the nature of the change is great.

Pull Request Overview

This PR performs a significant architectural refactoring that consolidates player state management by moving queue and playback state from Zustand store into the Player class itself, and replacing the MediaSessionEvents component with integrated MediaSession logic directly in the player.

Key changes:

• Merged player state management into a single Player class using EventEmitter for React integration
• Removed usePlayerStore Zustand store and PlayerStatus enum in favor of direct player instance usage
• Consolidated MediaSession event handling into the Player class constructor
