In this benchmark, compile/instantiate failures are handled by printing and returning, which makes
go testsucceed while silently skipping the wazero sub-benchmark. That can reintroduce the "missing benchmark results" failure mode (or leave README rows stale). Prefer failing the benchmark (e.g.,b.Fatalf/b.Fatal) so CI clearly reports the problem.
