/**
* @brief Retrieves the number of commands pending in the Nextion command queue.
*
* This function returns the current count of commands that have been queued but not yet processed
* for the Nextion display. The Nextion command queue is used to store commands that are sent to
* the Nextion display for various operations like updating the display, changing interface elements,
* or other interactive features. A larger queue size might indicate a higher processing time or potential
* delays in command execution. This function is useful for monitoring the command flow and managing
* the execution efficiency of the Nextion display interface.
*
* @return size_t The number of commands currently in the Nextion queue. This count includes all commands
* that have been added to the queue and are awaiting processing.
