Pull Request Overview

This PR adds a new "vibe" command that generates and plays a 15-song playlist based on user-specified mood/vibe using OpenAI. The implementation refactors the existing playback system to support multiple songs with queue management and enhanced playback controls.

Key changes:

• Implements the vibe command that creates mood-based playlists via OpenAI
• Refactors playback system to support song queues instead of single songs
• Adds new playback controls (next, previous, shuffle) with corresponding button handlers
