nanobyte-dev/nanobyte_os ? reverse-engineered prompt

Build me the OS project from this Nanobyte tutorial repo so it can compile and run in QEMU from a clean setup.

I want the whole thing to work end to end, including setting up the custom toolchain, building the image, and launching the OS with a simple run command. Please make sure the build steps are straightforward, and if there are any config values that need to be changed first, point them out in a way that’s easy to follow. If anything depends on current package or tool versions, check the latest docs online and use sensible defaults.

When it’s done, I should be able to follow the instructions, build successfully, and boot the OS without having to guess about missing dependencies or setup steps. If you spot any rough edges in the build scripts or README that would block a first time user, clean those up too.
