956be4b77a Add shade profiles, 2D V×I sweep, meter format toggle, ON/OFF indicators, and GUI console 
- Shade profile: CSV-driven irradiance/voltage sequences with load control
  (bench.run_shade_profile, CLI shade-profile command, GUI profile panel)
- 2D sweep: voltage × load current efficiency map with live graph updates
  (bench.sweep_vi, CLI sweep-vi command, GUI sweep panel with background thread)
- GUI: meter format selector (scientific/normal), supply/load ON/OFF indicators,
  console log with stdout redirect and color-coded messages
- Sample profiles: cloud_pass, partial_shade, intermittent_clouds

e2be7109b7 Add GUI control panel with live measurements and full instrument control 
New `mppt-gui` command launches a tkinter app with:
- Live numeric readouts for all 13 measurement channels
- 4-panel real-time matplotlib graphs (power, efficiency, voltage, current)
- Full supply control: voltage, current, OVP, slew, output on/off
- Full load control: mode (CC/CR/CV/CP), setpoint, slew, load on/off
- Meter settings: wiring mode, response speed, coupling per channel
- CSV data logging with start/stop control
- Red SAFE OFF button (also Escape key) bypasses command queue
- Threaded architecture: instrument I/O never blocks the GUI
- Fix apply() silently failing: use set_current + set_voltage instead

e55caa59b1 Initial MPPT testbench: unified CLI for IT6500D + Prodigit 3366G + HIOKI 3193-10 
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
