Spotify MCP Integration for Conversational Insights

Add a Spotify integration via MCP that allows users to interact conversationally with their Spotify data. This would enable queries about listening history, playlists, artists, and tracks, as well as generate personalized playlist suggestions, music discovery insights, and usage analytics directly within Notis. The integration should support both querying existing data and performing actions such as creating or modifying playlists. 🎧
