/**
 * Wraps a module's `createServer` so every server it hands out counts the
 * requests it serves.
 *
 * Its own module rather than a helper inside `bootstrap.ts`, because the
 * bootstrap is an entry point that runs on import and lands inside the
 * *measured* process — where no coverage instrumentation reaches it, and where
 * a mistake is only visible as a run whose numbers came from a process that
 * served nothing.
 *
 * `http.createServer` and `https.createServer` have different signatures, so
 * there is no shared type to borrow. Only the return value is touched, and the
 * arguments are forwarded untyped and unchanged.
