Add support for the M5Stack Cardputer ADV hardware variant, which replaces the original GPIO matrix keyboard with a TCA8418 I2C keypad controller. Changes: - Vendor Adafruit_TCA8418 library for I2C keyboard communication - Add MARAUDER_CARDPUTER_ADV board target with feature flags in configs.h - Implement TCA8418 keyboard driver with interrupt-driven FIFO scanning, coordinate remapping (verified against M5Cardputer-UserDemo-ADV), and persistent key state tracking for compatibility with menu polling - Extend all MARAUDER_CARDPUTER preprocessor guards to include ADV variant - Add TFT_eSPI display configuration (same display as original Cardputer) - Add CI build matrix entries for both parallel and nightly workflows
