/**
 * detach/drivers/setTimeout.ts — Defer detached work via `setTimeout(..., delayMs)`.
 *
 * Pattern:  Producer-consumer batch flush; deferral mechanism is
 *           `setTimeout` with a configurable delay (default `0`).
 * Role:     Cross-runtime "next macrotask" driver. Works in browsers,
 *           Node.js, Deno, Cloudflare Workers, Bun, etc.
 *
 * When to pick this:
 *   - Consumer wants a SPECIFIC delay (e.g. "ship telemetry in 5
 *     seconds, batched") — pass `createSetTimeoutDriver({ delayMs: 5000 })`
 *   - Cross-runtime detach where `setImmediate` isn't available
 *   - Coalescing high-frequency events into a low-frequency flush
 *
 * Caveats:
 *   - Not for low-latency hot paths — minimum delay is ~4ms in
 *     browsers per the HTML5 spec, ~1ms in Node. Use
 *     `microtaskBatchDriver` for sub-ms scheduling.
 *   - Browser tab freezing / throttling can extend the delay
 *     significantly. Don't rely on precise timing.
