Fix error in Attributes menu in World shading mode
Node Wrangler's Attributes menu allows direct addition of attributes
to a shading node tree. It only works on objects, not World, since the
latter does not store attributes.
Fix: Update Merge Nodes operator for new node types
Nodes were deduplicated between node modes (shading, compositing,
geometry) in Blender 5.0. This commit aligns Node Wrangler's Merge
Nodes operator to the new node types.
Cleanup
- Remove unused import and variables
- Merge Nodes Operator
- Use negative list indices instead of length - index.
- Chain conditions instead of nesting them.
