The host build works and staged llvm-native's .dev (static libs + cmake) so find_package(LLVM) now resolves — but the host clang binaries live in llvm-native's .runtime subpackage, which libclc didn't pull. The .dev -> .runtime package link does NOT transitively stage at build time, so libclc errored 'host clang not found under .../sysroot/usr/bin'. Move the entire host toolchain to dev-dependencies (build-only; libclc's shipped artifact is the .bc/.pc files, never clang) and add llvm-native.runtime explicitly so usr/bin/clang* is staged.
