- 实现了通过 SPI PING 命令获取 GD32 应用程序和引导加载程序版本信息 - 添加 /api/version HTTP 端点返回固件版本、编译时间和 Git 哈希 - 在系统状态 API 中包含 GD32 版本信息和存活状态 - 优化 SPI PING 协议解析以支持版本数据提取 refactor(ota): 移除压缩功能并简化 OTA 上传流程 - 移除 OTA 数据压缩和解压缩功能，简化数据处理流程 - 删除 utils/ota_compressor.cpp 文件及相关依赖 - 直接写入原始数据块而不是解压缩后写入 - 更新 OTA 上传处理器以处理原始二进制数据 build(cmakelists): 添加版本头文件自动生成机制 - 配置 CMake 构建时自动生成 version.h 头文件 - 集成 git 哈希和编译时间信息到固件版本 - 更新主 CMakeLists.txt 以包含版本生成目标 - 修改 app_config.h 以使用自动生成的版本字符串 fix(wifi_ota): 修复 OTA 中继状态管理和 SPI 通信问题 - 修复 OTA 中继完成后立即重置的问题，增加 3 秒延迟让前端轮询完成 - 修正 SPI CRC 错误检测和调试信息输出 - 优化 SPI PING 通信超时和重试机制 - 修复 OTA 上传大小计算和数据写入偏移跟踪
