Extend the examples/elf ROMFS path so nxpkg validation can use generated package fixtures instead of hand-managed metadata. Generate index.json, bad-index.json, pkgtest.nsh, and pkgfail.nsh from the built hello ELF, recording the correct target arch/compat metadata and SHA-256 digest for the valid fixture. Keep mismatched- target and missing-artifact cases alongside the valid fixture so nxpkg target selection and failure handling can be exercised from the same example tree. Group the paired fixture outputs in one make step so parallel builds do not re-enter the generator independently. This keeps the fixture metadata tied to the actual built hello artifact instead of relying on manually maintained hashes or ad hoc shell setup, making follow-up review and later test reruns more predictable. There is no intended loader or board-behavior change; this is limited to fixture generation inside examples/elf.
