Add util/fetch-gnu.sh (downloads the GNU grep 3.12 release tarball from ftp.gnu.org) and util/run-gnu-testsuite.sh, which reuses the gnulib test framework shipped in the tarball (tests/init.sh + init.cfg) and injects the Rust grep binary via PATH, replicating tests/Makefile.am's TESTS_ENVIRONMENT. Each test is classified by its gnulib exit code (0=PASS, 77=SKIP, else FAIL) and results are emitted as JSON. Modelled on ../sed (lightweight PATH-injection runner) and ../coreutils (release-tarball fetch). Current baseline: 61 pass / 39 fail / 28 skip of 128 tests -- the failures quantify the remaining GNU-compatibility gap.
