小龙虾 5db3f66b8e feat(protocol): 更新SPI Link协议至v2版本并优化CAN通信
- 将SPI OTA帧格式升级为SPI Link v2,采用新的帧格式:
  | SOF0 0xA5 | SOF1 0x5A | VER 0x02 | FLAGS | SESSION 4B LE |
  TX_SEQ | ACK_SEQ | CREDIT | TYPE | LEN 2B LE | RSV 2B | PAYLOAD |
  CRC32 4B LE |
- 新增V2_OVERHEAD=20字节开销,APP最大payload为236字节,BOOT为108字节
- 修改帧类型定义:ENTER_BOOT从0xB5合并至0xB0,新增CAN业务类型0xC0~C3
- 更新CAN协议文档,支持SPI Link v2-only模式,调整最大业务payload计算
- 扩展0xC1帧功能,支持双向通信和1Hz主动推送ID快照
- 添加0xC3完整ID快照帧类型,包含seq/rx_count等完整字段
- 更新协议文档中的错误码定义和反馈payload格式

refactor(main): 重构主程序入口并添加CAN反馈任务

- 在main.cpp中添加CAN反馈任务,更新启动流程注释
- 创建createCriticalTask辅助函数,统一关键任务创建逻辑
- 调整SPI初始化顺序,确保CAN反馈任务依赖正确
- 优化错误处理机制,关键任务失败时立即重启
- 将GD32版本探测移至ota_relay任务处理
- 更新版本号至0.3.48,调整编译时间和Git哈希

config: 更新SPI和BLE配置参数

- 添加SPI主机相关配置参数,包括CS GPIO、READY GPIO等引脚定义
- 配置SPI缓冲区大小:APP为256字节,BOOT为128字节
- 更新BLE滑动窗口参数,ACK窗口设为32,数据队列深度为72
- 调整SPI工作队列大小至5120字节,增加任务堆栈监控说明
