Catalog Studio: - Cross-parent drag & drop now uses optimistic updates with rollback on failure (no more full tree reload / visible delay) - Subpage creation adds the node optimistically then refreshes parent only (was full tree reload) - Single page deletion refreshes only the affected parent (was full tree reload) - Root page creation replaces native prompt() with an inline input in the root tab bar - Escape key no longer closes the dialog when an input field is focused - TreeNodeUpdate type now supports parentId and orderNum for optimistic structural changes Docker: - docker-prune.sh default mode now aggressively cleans all unreferenced build cache, images >1h old, and stopped containers >1h old (was 72h/7d/24h which let cache grow past 80% on every push)
