Perf Benchmarker

If you're chasing down performance regressions or establishing real baselines, this enforces the discipline most benchmark scripts skip. It mandates 60 second runs with proper warmup, blocks parallel execution that pollutes results, and makes you re-run anomalies instead of cherry-picking good data. The tool expects structured JSON output between markers and won't let you take shortcuts with quick 5-second tests unless you're actively binary-searching for a threshold. It's opinionated about measurement rigor, which is exactly what you need when numbers actually matter for production decisions.
