feat: 实现智能按摩器完整功能 (定时/语音/电机/显示)

- 新增MP3语音模块驱动，集成18个语音提示，支持播放/停止/音量调节
- 实现0/10/20/30分钟循环定时倒计时，实时显示剩余时间，定时结束自动停机
- 优化电机控制：一档力度提升至75%，降档冲击时间延长至800ms，降档时触发100%冲击防卡顿
- 屏幕显示重构为分区动态更新：时间状态(Zone1)/档位(Zone2)/加热(Zone3)，性能优化
- 新增LED指示：运行时RUN_LED以500ms周期闪烁，无效操作ERR_LED亮1秒
- 操作逻辑改进：所有操作需先设定时间，否则播放"请先设定时间"并亮ERR_LED
- 加热控制由GPIO改为PWM(TIM1_CH1)，占空比300
- 调整USART3波特率为9600适配MP3模块
- FreeRTOS任务优化：Motor周期500ms，Screen周期10ms，新增定时器秒Tick处理
- 完善开发文档：MP3集成指南、校验和验证脚本、文件重命名工具等

新增文件：mp3_driver.h/c, 多项开发文档
修改文件：freertos.c, gbk_text.h/c, motor_driver.c, screen.h/c, usart.c, gpio.c等
