//! # HTTP Response Utilities
//!
//! This module provides comprehensive utilities for working with HTTP responses.
//! It includes functions for creating, manipulating, transforming, and filtering
//! HTTP response codes and messages in various formats (JSON, XML).
//!
//! The module supports:
//! - Looking up response information by code or type
//! - Transforming responses to JSON and XML formats
//! - Filtering responses by code ranges
//! - Creating enriched responses with metadata
//! - CORS validation for responses
//!
//! These utilities are designed to provide a consistent API for handling
//! HTTP responses throughout the application.
