aced4f1e23 Add CP load mode to 2D sweep and supply sanity checks 
- 2D sweep now supports CC (constant current) and CP (constant power)
  load modes via --load-mode flag (CLI) and combobox (GUI)
- Supply capability check before all sweeps: validates max voltage
  against supply range and prints V/I/P summary
- Renamed sweep-vi args from --i-start/stop/step to --l-start/stop/step
  to reflect that the load setpoint can be current or power
- GUI labels update dynamically based on selected load mode

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

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
