# build_all.sh — Master build orchestrator for hiperiso
# ---------------------------------------------------------------------------
# Runs the full pipeline:
#   1. download sources
#   2. build host kernel (KVM built-in)         -> staging/vmlinuz
#   3. build stripped QEMU                      -> staging/qemu-system-x86_64
#   4. build OVMF firmware (SMM + Secure Boot)  -> staging/OVMF.fd
#   5. build GRUB2 with hiperiso module         -> staging/BOOTX64.EFI
#   6. build busybox (static)                   -> staging/busybox
#   7. build hiperiso-log tool                  -> staging/hiperiso-log
#   8. pack initramfs                           -> staging/initramfs.cpio.gz
#   9. build GUI/tool payload                   -> build/payload/
#  10. assemble final distributable payload     -> build/payload/
