Two bugs:
1. Dropped nodes were pushed to the end of the pipeline, but the Output
node already sat there from startup. The cycle validator and the
compiler only look for sources at indices strictly lower than the
target, so new nodes were invisible to the Output. Fix: insert
dropped nodes before the first Output; topo_sort also stable-moves
Output nodes to the back.
2. ColorEdit3 with default flags rendered RGB text inputs alongside the
swatch; clicking them dragged the node instead of opening the picker.
Fix: NoInputs + NoLabel leaves only the swatch (a single item), and
ed::Suspend/Resume wraps the call so the popup isn't clipped to the
node or captured by the canvas.
