/**
 * Structured HTTP request logging middleware for Hono.
 *
 * Logs every request with method, path, status code, latency, and
 * content-length. In production, outputs JSON for Cloud Logging; in
 * development, emits a coloured one-liner.
 *
 * @example
 * ```ts
 * import { requestLogger } from "@rebasepro/server-core";
 * app.use("/*", requestLogger());
 * ```
