- Add comprehensive README with wiring diagram, CLI reference, and examples
- Fix supply VISA timeout during sweeps: read supply/load before meter wait,
add retry wrapper for instrument queries, keepalive ping during auto-range
- Fix load_setpoint not recorded in voltage sweep CSV
- Add load current sweep command (sweep-load)
- Increase HIOKI auto-range wait to 30 retries x 2s

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
