/**
 * Benchmark runner for Node, Bun, and Deno.
 *
 * How to run:
 * - Node: `node --expose-gc bench/bench.ts`
 * - Bun:  `bun bench/bench.ts`
 * - Deno: `deno run --allow-read bench/bench.ts`
 *
 * Notes:
 * - GC is optional; when available, it is invoked before each run to reduce noise.
 * - If results are too noisy, increase RUNS, ITERS, or BATCH.
