- Add visible typed ports on graph nodes (colored dots for each edge type)
- Route edges to specific port positions instead of node center
- Drag from output port to compatible input port to create/change connections
- Right-click edge context menu with Disconnect option
- Delete key detaches selected edge
- Mark nested edges (composite layers, zones) as non-editable with dotted style
- Add resolve_ref helper for empty-string sentinel to clear reference fields
- Apply resolve_ref across all storage stores for consistent detach support
- Add connection mapping module (graph-connections.js) with API field resolution
- Add i18n keys for connection operations (en/ru/zh)
