Keep one PM invariant (a musl ELF userland resolves to linux-<arch>-musl and the default closure is satisfiable with musl-native artifacts) and one installer invariant (uv_bootstrap_target picks musl uv from a musl ELF interpreter even when ldd says glibc). Drop the lock-content and URL-shape change-detectors.
