addCustomWidget failed silently in this ComfyUI version. Switch to
node.addWidget("button",...) which is natively supported. Also add the
same hideWidget retry timing pattern Scene Builder uses (rAF + two
setTimeout calls) so the adjustments text widget reliably disappears
after the node is created or reconfigured.
