test/lib/guest.mjs runs a guest on the page's shim directly through run-node.mjs, below the runtime API, on the node host. It builds programs from fixtures/programs (zig musl, gcc or zig glibc), caching each by its content in the work directory. It also makes seeds with gexc, finds the loader and libc a glibc program needs (the host's, or A64_ROOTFS's), runs the single-thread build, and lists the page's legs per arch. A missing piece is a skip. The new page group holds output-order, exec-relative, pipe-eagain, mkdir-parent, thread-signal, mtime, panic, poll-timeout, reuse, dethread and spawn. Each script's checks are kept, on both arches with the single-thread leg where the script had one. A test's meta can now name its arches.
