Lazy connect nodes

Feature to connect two nodes without clicking the sockets directly.
Hold the modifier key then click and drag from one node to another, the nodes nearest the start and end points will be selected.
Sockets are selected based on similar types or order priority.

Blender has this feature https://docs.blender.org/manual/en/latest/addons/node/node_wrangler.html#lazy-connect
Blender uses `Alt-RMB` shortcut

No file, test, or entry point is named. Begin with the linked Blender lazy-connect reference and trace the node editor’s drag and socket-selection entry points; done means modifier-drag connects the nearest nodes and chooses compatible sockets by type or priority.
