- 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
