subhobhai943/SUB-OS ? reverse-engineered prompt

Build me this operating system project so I can boot it in an emulator and explore the userland tools.

I want the whole repo wired up into a working 64 bit OS image with a clean build flow from the Makefile, plus a simple way to configure it and run it in QEMU. Please make sure the kernel, boot code, drivers, filesystem, networking, and the LazyBox userland pieces all build together without missing steps. If anything is unclear from the repo, look up the current docs online and use the project’s existing style.

I’d also like a straightforward startup experience, so it should boot, show a shell or menu, and let me try the built in commands and demos like the snake game, filesystem access, and basic networking tools if they are already present. If there are broken paths, missing glue code, or build issues, fix them and leave the project in a state where someone can clone it, build it, and boot it successfully.
