Apps/Explorer：复制标准 app 骨架（main.vp / linker.ld / project.vpj，链接地址 0x400000）。启动流程：open /dev/fb0 → ioctl(FB_GET_INFO) 打几何 → mmap 拿到线性地址 → 等约 2 秒（等内核桌面首屏全量重绘过去）→ 画一条渐变横条验证像素真上屏 → open /dev/input/keyboard|mouse 验证输入设备可达 → 常驻不退出。 vpsdk/devfs.vp（新增 SDK 设备层）：设备路径常量（与内核注册名逐字一致）、FB_GET_INFO 与 FbInfo 镜像（packed，与内核同布局）、fb_open/fb_get_info/fb_map/kbd_open/mouse_open。 build.py：把 Explorer 加进 required_apps 清单与完整构建分支；内核 main.vp 在四个 app 之后 spawn /APPS/explorer.elf。内核 desktop 与 explorer 并存属迁移中间态，S3 会把窗口合成整体交出去。
