refactor(device): 重构SPI命令处理为模块化架构

Browse Source 
- 将原有的 monolithic app_spi_command.cpp 拆分为多个专门的命令处理器文件
- 新增 spi_command_handler.h 定义命令处理器接口和上下文结构
- 新增 app_spi_command_defs.h 提取公共协议常量定义
- 新增多个具体命令处理器实现文件：
  - app_spi_cmd_boot_request.cpp (进入Bootloader命令)
  - app_spi_cmd_ota_wait.cpp (OTA等待响应命令)
  - app_spi_cmd_ping.cpp (APP心跳ping命令)
  - app_spi_cmd_can_bridge.cpp (SPI到CAN桥接命令)

- 修改 app_spi_command.cpp 仅负责SPI链路管理和命令路由逻辑
- 更新配置文件添加新源文件到项目编译列表
- 调整全局实例为对象实例(AppSpiCommandBus)，移除静态方法依赖
- 更新README文档说明新的SPI命令总线拆分架构
- 微调版本号(patch: 0 -> 1, build: 2 -> 0)

/**
* @file app_spi_command.cpp
* @brief APP 运行期 SPI 命令从机实现。
* @brief APP 运行期 SPI 链路与命令路由实现。
*
* 复用 BOOT 的 SpiOta 协议帧格式（SOF+TYPE+LEN+PAYLOAD+CRC），
* APP 只处理进入 Bootloader 命令（TYPE=0xB0），
* 收到 OTA 命令帧（TYPE=0x01/0x02/0x03）时回复 WAIT 帧告知
* ESP32 "当前不在 BOOT 模式"。
* 本模块现在只负责：
* - SPI0 从机链路初始化（GPIO/SPI/DMA/EXTI）
* - CS、DMA、中断驱动的帧接收与发送
* - 公共帧格式解析与应答构建
* - 业务命令的注册与分发
*
* 调试日志采用延迟输出：processCommand() 只写 s_logBuf + 置 s_logPending，
* 同时置位 TASK_SPI_LOG 唤醒主循环，poll() 中立刻 printf。
* 具体命令处理逻辑已经拆到独立的 `app_spi_cmd_*.cpp`，
* 通过 `registerHandler()` 注册进来，后续新增 SPI 业务时
* 只需要新增命令处理器，不再继续膨胀本文件。
