Functions
esp_err_t	input_init (void)
	Bring up the input service: queue, both ISRs, the input task, and A's wake-ready pin.
bool	input_get_event (ui_event_t *out, TickType_t ticks_to_wait)
	Block until the next input event (the UI task's read side of the queue).
uint32_t	input_idle_ms (void)
	Milliseconds since the last button event was emitted.
void	input_get_diag (input_diag_t *out)
	Read the current button state and per-button press counts.
