nx_recycler_bench_measure.nx

nx_recycler_bench_measure.nx -- turn the benchmark's BETTER scores from design-facts into MEASURED numbers (no-wave / measured-exceed). It measures, on THIS machine, a trivial native Nishi ELF (nx_min): (1) STARTUP = avg fork+exec+exit time over N runs via the monotonic microsecond clock; (2) BINARY SIZE = the ELF's byte count. HONEST: Nishi's numbers are MEASURED here; the competitor baselines (JVM cold start, runtime size) are DOCUMENTED / well-known and explicitly NOT run by us (we don't ship a JVM). Build nx_min first so /tmp/nx_min.sov.elf exists; run this ELF DIRECTLY (it forks). Self-gating. license_tier: ORIGINAL
