EXIF info panel: - New on-demand get_image_exif command (kamadak-exif) returning camera/lens/ aperture/shutter/ISO/focal-length and decimal GPS; read from the file when the lightbox opens (no DB schema change, works on already-indexed images). - Lightbox shows a Camera panel; GPS opens the location in the browser via OpenStreetMap (adds opener:allow-open-url capability). Tag management: - Backend rename_tag (rename, or merge when the target exists) and delete_tag (library-wide), both clearing the tag-cloud cache; store actions invalidate tag caches, refresh Explore, and re-point/refresh an active tag-search. - Explore -> Tag Cloud gains a Manage mode: a flat list with per-tag rename/ merge/delete. Albums: - Drag-to-reorder in the sidebar via framer-motion Reorder with a hover handle; order persists through the existing reorder_albums command. Reads live store order on drag end and robustly derives GPS hemisphere from raw EXIF ref bytes (review follow-ups). CHANGELOG updated.
