Feature: AI-powered personal DJ and curator

[PetalCat]

Summary

Using StreamyStats AI embeddings + Jellyfin music + Lidarr:

• "Generate a playlist for cooking dinner"
• "Movie marathon for a rainy Sunday"
• "Background music that matches what I'm reading"
• Context-aware recommendations based on time of day, recent activity, mood

Why

StreamyStats already has OpenAI-compatible embedding support. Nexus can feed it cross-media context that StreamyStats alone doesn't have.

Implementation

StreamyStats AI chat API + context injection from Nexus activity data + Jellyfin instant mix API.
