/**
 * @file app_spi_command.cpp
 * @brief APP 运行期 SPI 命令从机实现。
 *
 * 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"。
 *
 * 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。
