- Removed unused constants and type aliases in app_spi_command_defs.h and temp_sensor.h. - Simplified ISpiCommandHandler destructor to default. - Eliminated redundant methods and comments in temp_sensor and usart0 files. - Consolidated writeU32Le function to app_spi_command_defs.h for reuse. - Updated comments for clarity and accuracy in task_manager.h and task_runner.cpp. - Removed hardfault.h as it contained no declarations. - Cleaned up CANFD and watchdog implementations by removing dead code and unnecessary comments. - Updated version numbers in config.h to reflect recent changes. - Enhanced error handling and diagnostics in hardfault handling.
