A build system for C++26 modules. Project descriptions are C++: a project.cpp constructs a Configuration and returns it, and crafter-build compiles, loads and executes it. The Flatpak carries its own LLVM, so every machine builds with the same clang, lld, libc++ and WASI sysroot.
First release distributed as a Flatpak, with a bundled LLVM 22 toolchain and WASI sysroot. Windows host support is removed; crafter-build gains --version and resolves its compiler from one place.
