ludic-dev vkgen reads vk.xml into runtime/native/vk_api.ludic (constants, every struct's
<Struct>_sizeof and <Struct>_<field> offsets, one extern per command) and vk_thunks.ll.
Every size and offset was compiled against the SDK's C headers; `ludic-dev test` checks the
tracked files against the registry wherever the Vulkan SDK is installed.
vk_win.ll (vulkan-1.dll) and vk_mac.ll (libvulkan.1.dylib, MoltenVK) open the loader at run
time, so a program built with Vk.* starts on a machine without Vulkan. ludicc and ludic
build link both for any program that uses Vk.*. The seeds are regenerated for the new
compiler.
vk_probe reports what a machine's Vulkan can do; vk_compute dispatches a Slang compute
shader and reads the picture back, clean under the validation layer on an RTX 3070 Ti and
on an M4 Pro through MoltenVK.

The CLI's shell commands go through shell(), which is run() on POSIX and a
scratch script handed to Git for Windows' bash on Windows (exit codes read
directly there). compile_app links through `ludicc -o` on Windows, ludic run
starts the .exe, and ludic-dev build and ensure_ludicc assemble
selfhost/ludicc.win.seed.ll, which ludic-dev reseed now writes beside the
macOS seed. ludic bundle makes build/<name>/ with a GUI-subsystem exe carrying
the .ico beside `app icon` as an llvm-rc resource, game.lpak and packs.index;
ludicc gains --gui and --link, and quotes its whole link line for cmd.exe.
Verified: ludic-dev test 135/135, selfhost-test 32/32; on the PC a checkout
bootstraps from the Windows seed, ludic-dev build makes the toolchain, and
`ludic bundle` makes build/Maroon Lake/, which runs from its own folder.
