- GUI: voltage/current range selectors for Ch5 and Ch6 with AUTO option
- Worker: queries current V/I ranges each poll cycle, pushes to GUI
- Setting a fixed range automatically disables auto-range for that channel
- Live display shows current range values below each channel's readout

Combines three instrument drivers (as git submodules) into a single
testbench for MPPT tracker efficiency testing. Features:
- Voltage sweep and load current sweep with CSV export
- Auto-range aware meter polling (waits for HIOKI to settle)
- Supply keepalive during long meter waits to prevent USB-TMC timeouts
- Live monitoring with real-time 4-panel matplotlib graphs
- Safe shutdown (load first, then supply)
- Post-sweep returns to 75V idle with supply ON
