Add sortOrder column to diagrams, extend PATCH endpoint with projectId and sortOrder fields, add POST /diagrams/reorder bulk endpoint with ownership verification and duplicate ID validation. Enhance RecentList with lastAiMessage preview subtitle. Implement @dnd-kit drag-and-drop in ProjectTree sidebar with cross-project moves, intra-project reorder, optimistic updates, drag overlay, drop indicators, and keyboard/pointer sensor support. Context-aware GET ordering: sortOrder for project views, updatedAt for recent/all views. 141 tests pass. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
