- UartBus -> USART (类名更符合外设命名规范) - 构造函数 USART(UartPort port, uint32_t baudrate) 自动完成GPIO+外设初始化 - 移除default_instance()单例模式，移除init()/deinit()/irq_handler() - 新增reinit(baudrate)支持时钟切换后波特率重新校准 - 新增static setDefault()用于printf路由选择 - 移除UartConfig配置结构体 - 更新iap.h/iap.cpp中UartBus引用为USART - 更新main.cpp使用新USART构造模式
