/**
* @brief Check if the Nextion display is successfully connected.
*
* This method returns whether a successful connection has been established with
* the Nextion display. A connection is considered established when:
*
* - The initial handshake with the display is completed successfully, or
* - The handshake is skipped via skip_connection_handshake_ flag
*
* The connection status is particularly useful when:
* - Troubleshooting communication issues
* - Ensuring the display is ready before sending commands
* - Implementing connection-dependent behaviors
*
* @return true if the Nextion display is connected and ready to receive commands
* @return false if the display is not yet connected or connection was lost
