- Enable BTN_FWD_GPIO (GPIO 10) as secondary button for mode toggle (Shift+Tab) - Update BOARD_HAS_SECONDARY_BUTTON flag from 0 to 1 - Clarify button layout: BOOT (primary PTT), PWR (cycle screens via AXP), KEY (secondary mode toggle) - Document KEY GPIO discovery method (empirical scanning of unused GPIOs) - Update button_count calculation to include secondary button when available - Initialize both BTN_BACK_GPIO and BTN_FWD_GPIO in input_hal_init() - Refactor input_hal_is_held() to use switch statement for cleaner multi-button handling
