Hovering a tag in Explore now loads and displays co-occurring tags as a weighted cloud. New `get_related_tags` SQL self-join (db.rs/commands.rs), `loadRelatedTags` store action with per-folder keyed cache, and TagCloud atlas UI with ResizeObserver-driven layout and RAF animation. Explore tag limit raised to 180; tag cloud auto-refreshes 700ms after new AI tagging completes.
