内核 intr/syscall.vp 与 vpsdk/syscall.vp 各一份 1..34 的 define 表改为同名 enum Syscall。编号口径：与 Linux 同名同号；Linux 有而我们未实现的留空不占号（12 brk / 39 getpid / 84 rmdir / 217 getdents64 / 257 openat … 需要时按号补）。 15 个语义重合的调用直接用 Linux 号：READ 0 / WRITE 1 / OPEN 2 / CLOSE 3 / STAT 4 / SEEK 8 / MMAP 9 / MUNMAP 11 / YIELD 24 / THREAD_CREATE 56(≈clone) / SPAWN 59(≈execve) / THREAD_EXIT 60(exit) / MKDIR 83 / REMOVE 87 / EXIT 231(exit_group)。 其余 19 个（UI 11 个 + SERIAL_PUTS/TELL/SIZE/OPENDIR/READDIR/CLOSEDIR/LOAD_SO/SO_CALL1）暂放 0x1000 起的**临时私有段**，每条带迁移标注：私有能力最终不占 syscall 号、改走 devfs 设备文件；UI 11 个待用户态 explorer（图形壳）接管 framebuffer 与输入后删除。 内核派发链改 n == int(Syscall.X)（n 是 int/i64、成员是 i32，显式 int() 规避未证实的混合宽度比较）；SDK 全部调用点统一为 syscall.Syscall.X；stdlib 的 SYSCALL_MMAP 别名并入 Syscall.MMAP；Terminal 里硬编码的 uint64(18) 改为常量。
