Label and Get/Set-Node

### What problem are you experiencing?

Would it be possible to natively add labels and global value definition nodes to Comfyui Fronted, such as rgthree/label or KJNodes/(Get,Set)Node?

These two features seem essential for any node-based editor, and installing rgthree and KJNodes (hundreds of nodes) just to use what appears to be the bare minimum for this type of IDE is quite tedious.

(It's like using a bulldozer to plant a tulip!)

The issue names no repository files, tests, or entry points. Compare the requested native label and Get/Set-Node behavior with rgthree/label and KJNodes/(Get,Set)Node, then define the frontend scope and acceptance criteria before implementation.
