task zy: move GUI application launch out of Processor into cmd/main.go [SoC]

Replace Processor.RunGUIMode() with a standalone runGUIMode() function in
the composition root (cmd/main.go) that calls proc.GUIConfig() to get the
GUI settings and then owns the gui.New()/Run() lifecycle. The processor
package still imports gui for the gui.Config return type; complete removal
of that import is deferred to task 000 (god-object decomposition) where
the Processor itself will be split up.
