copy/paste for nodes is just... not there

[avinxshKD]

Can't copy a node, can't paste one. Ctrl+C/Ctrl+V do nothing. There's no clipboard state, no copy/paste functions in toolbarFunctions.js, nothing in toolbarList, the feature just doesn't exist anywhere in the codebase.

For anything beyond a trivial graph this is genuinely painful. Want to reuse a node pattern? Rebuild it by hand every time.

Needs copy/paste wired up end to end clipboard state in the reducer, copySelected() and pasteClipboard() methods on the graph instance, functions in toolbarFunctions, toolbar entries + Ctrl+C/Ctrl+V hotkeys in toolbarList.

Hey @pradeeban hit this while editing a bigger graph. I checked and couldn’t find node copy/paste wired anywher (no reducer clipboard state, no toolbar/hotkey handlers), so it looks like the feature is just missing right now. I can take this up if you want.

Feels like a useful addition.

@avinxshKD sure, go ahead! It is something that we never thought about before actually! But a useful feature regardless.
