Real WASM validation during kernal-api migration found the installed 4.0.21 package cannot pass its static health check: LLVM_ROOT and BINARYEN_ROOT in .emscripten still name the removed staging directory. install_spec writes config and optionally health-checks before renaming staging to its final package path, but does not relocate that config. Existing archive config tests only write directly to final paths and miss the lifecycle. Fix installation publication and existing managed installs without changing compiler version or JSPI defaults; add a staging-to-final regression and rerun real compiler health plus Blink compile. Refs #242 and zackees/kernal-api#205.
