Use Metasm's asm("db ...") to embed shellcode directly in .text section
which is executable by default. Removes mmap/memcpy/mprotect entirely,
avoiding RWX or W^X allocations that IDS may flag.
Parent process uses _exit(0) instead of return since the inlined
shellcode bytes follow the setsid() call in the instruction stream.
