feat(discover): content discovery panel with For You, tags, playlists, collections (M13.1-M13.8)

- For You feed: frequency map from favorites, sorted by most-favorited type
- Content tagging: user tags on any item, tag cloud, filter by tag
- Smart playlists: recently played, most played, by genre, by decade
- Similar content: background AI call for 3 suggestions, cached 7 days
- Recently viewed history: last 50 items with time-ago display
- Content collections: user-curated mixed-type lists with mosaic grid
- Trending: most-referenced items across 30 days with badge
- Share to Nostr: compose preview, sign via NIP-07, broadcast to relays
