Version Check Pixaroma

Version Check Pixaroma - a small on-canvas panel showing the versions that matter when reporting a bug: the ComfyUI (backend) version, the ComfyUI frontend version, which node interface is active (Nodes 2.0 / Legacy), and the installed Pixaroma version. A Copy button copies all four lines as text so you can paste them straight into a bug report. Pure diagnostic - no inputs to wire, no outputs to chain, no Python work on Run. The Node UI row updates live when you switch the setting.
