- 用户态共享网络协议栈 CODE/tools/net_stack.h（eth/ARP/IPv4/ICMP/UDP-DNS/TCP static inline，轮询模型） - shell 内建 ping/curl/run 命令；ping.elf/curl.elf 对齐 net_stack.h 真实协议栈 - shell dev_mode 串口镜像（g_serial_mirror）便于自动化验证 - DSK 启动流程：firstInit.txt 双行格式（firstInit + dev_mode），dev_mode=1 触发 shell 自动回归测试 - FirstInit 完成→持久化 USER.CONF + 翻转 firstInit 0->1（保留 dev_mode） - firstInit=1 时 DSK 加载 login.elf 进行用户选择 + 密码校验后再进 desktop - 新增 CODE/login/ 登录应用、CODE/DKM/dkm_shared.h、Logo.png - ahci/e1000/virtio_net/fat32/console_fb 驱动更新；utsm serial/block/dsk_loader 调整 - build.ps1 打包 ping.elf/curl.elf 进 SATA FAT32 根目录 - 移除 CODE/tools/bash（与 shell.elf 重复）
