/**
 * @file meshx_model_def_trans_time.hpp
 * @brief Implementation of Generic Default Transition Time Model for MeshX
 *
 * This file contains the implementation of the Generic Default Transition Time model,
 * which provides standard Default Transition Time model functionality in the MeshX BLE mesh framework.
 *
 * Key Features:
 * - Implements Bluetooth SIG-defined Generic Default Transition Time model
 * - Inherits from meshXClientModel and meshXServerModel templates
 * - Provides standard Default Transition Time control operations
 * - Integrates with MeshX transmission control
