Add sude/GuiTest.json - small, fast schedule for exercising the GUI

6 steps covering a plain ramp, a wait-for-confirm step, a plain hold,
a combined ramp+hold (up), a combined ramp+hold (down, exercises
COOL), and a final confirm - all small temperature deltas and 1-minute
holds so a full run finishes in well under a minute at typical warp
factors, for quickly cycling through Load/Start/Pause/Stop/restart
scenarios without waiting through a real brew.
