Adds an automatic Arduino Uno production-test sketch derived from the completed GP8403 QT Tester schematic and board.\n\nThe test verifies:\n- boosted 12 V rail on A3\n- all eight hardware I2C addresses from 0x58 through 0x5F\n- VOUT0/VOUT1 through the A1/A2 divider inputs in both 5 V and 10 V ranges\n- green pass LED and buzzer status outputs\n- safe output clearing on pass and failure\n\nNVM is intentionally not written.\n\nVerified locally and independently by Terra for arduino:avr:uno with all warnings enabled: 12,054 bytes flash, 451 bytes SRAM, zero warnings.
