feat: Phase 1 网络端到端打通 + FirstInit/Login/DevMode 完善

Browse Source 
- 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）

/* DKM 共享头文件 — 消除各驱动重复的结构体/宏/PCI/TSC 代码
*
* 设计要点:
* - 结构体定义与 UTSM/include/utsm/dkm.h 保持布局一致 (canonical)
* - PCI I/O 函数使用 static __inline__, 每个 .drv 文件获得独立副本, 避免链接冲突
* - TSC 校准函数使用 static __inline__, 每个 .drv 文件获得自己的 dkm_tsc_per_ms
* - 驱动源文件只需 #include "../dkm_shared.h", 保留各自的 driver_desc 和 driver_init
*
* 使用约定:
* 1. 在 driver_init 开头调用 dkm_tsc_calibrate() 完成校准
* 2. 时序等待使用 dkm_delay_ms() / dkm_delay_us()
* 3. 串口发送等待使用 dkm_serial_wait_tx(COM1)
* 4. MMIO 寄存器读取等待使用 dkm_rdtsc() + dkm_tsc_per_ms 直接计算 deadline

/* net_stack.h — Deshab 用户态共享网络协议栈（static inline，无库）
*
* 前置条件：包含者已定义 u8/u16/u32/u64/i64 基础类型。
* 通过 dkm_kernel_api + 0x48 的 net API 收发原始以太帧（轮询模型，无 IRQ）。
*
* 能力：eth II / ARP（含应答）/ IPv4 / ICMP echo / UDP DNS / TCP 最小 client。
* 默认拓扑：QEMU slirp — guest 10.0.2.15 / gw 10.0.2.2 / dns 10.0.2.3。
*
* 用法：
* ns_init(ctx->dkm_kernel_api) — 初始化，选第一个有线 tx/rx ready 设备
* ns_ping(ip, seq, timeout, &rtt, &ttl) — 单次 ICMP echo
* ns_dns_resolve(host, &ip) — A 记录查询（数字 IP 直接返回）
* ns_tcp_connect(ip, port, timeout)
* ns_tcp_send(data, len)
* ns_tcp_recv(buf, cap, idle_timeout) — 收至 FIN/超时，返回累计长度
* ns_tcp_close()
*
* IP 以 u32 网络序数值表示（NS_IP4(10,0,2,15)）。
