SPI Link v2 Self-Test / selftest (push) Has been cancelled
添加SPI Link v2的PC端自测功能，包含交叉校验基准测试，覆盖HELLO/OTA/CAN/PING等 多种协议场景。同时重构了health monitor中的多字段读取逻辑，消除了volatile变量 的撕裂读问题，并增强了BLE OTA的数据传输可靠性。 refactor(health_monitor): 修复heap hook多字段撕裂读问题 采用portMUX_CRITICAL临界区实现多字段一致快照读取，消除任务上下文与heap hook 之间的数据竞争。修改了HookSnap结构体设计，通过一次性拷贝volatile变量避免 跨字段组合时的数据不一致。JSON输出中明确标注estimated值的置信度。 fix(ble_ota): 实现DATA_IN丢包负反馈机制 当malloc失败或队列满时发送缺口ACK通知前端按completed_bytes续传，避免 静默丢包导致的8秒超时重传风暴。增加节流机制防止负ACK在重传叠加时打爆 NimBLE mbuf池，提升低内存环境下的OTA传输稳定性。 refactor(spi_master): 从堆分配改为固定Job池管理 将SPI worker的动态堆分配Job改为固定大小的静态池管理，避免频繁的 calloc/free操作影响实时性。新增acquireJobSlot/releaseJobSlot机制 管理池槽生命周期，提升SPI通信的可靠性和内存使用效率。
