LightFM in Python: Fix New-Item Cold Start with Metadata

LightFM folds item metadata into WARP-trained embeddings to solve the recommender cold-start problem. Follow a compact Python workflow to rank new items from tags/categories, compare hybrid vs interaction-only models, and evaluate with precision_at_k using LightFM (Dataset, WARP). Get a reproducible prototype for surfacing zero-click items and practical tips for scaling and tuning no_components/item_alpha.
