* @details This file contains the main execution program for an Arduino-based

* Modbus RTU protocol over a serial connection.
*
* The setup() function initializes the following:
* - Serial communication for debugging.
* - A Modbus RTU server with parameters from config.h.
* - Modbus points (Coils, Holding Registers, etc.) based on a predefined map in config.h.
*
* The loop() function continuously:
* - Services the Modbus RTU server to handle incoming requests.
* - Periodically calls the main update loop for the emulated equipment, which
* manages state transitions and behavior strategies.
*
* @see config.h for Modbus RTU and register map configuration.
* @see Equipment.h for the main equipment logic.
* @see State.h for different equipment states.
* @see Strategies/Strategy_Behavior.h for value generation strategies.
* @see Modbus_Point.h for the base class for all Modbus points.
