Drive identical wire scenarios across several spawned backends and time each round trip, so a TS impl and a Rust impl can be compared apples-to-apples (both cross-process over real HTTP). The reusable cross-impl measurement primitive.
fuz_util's benchmark library is the engine — Benchmark runs each scenario
as a task and BenchmarkResult.stats carries the percentiles; this module
is the thin scenario→task→tagged-result adapter. Reporting (markdown,
TS-vs-Rust verdict, JSON artifact) lives in testing/cross_backend/bench/bench_report.ts.
