//! # MockForge HTTP
//!
//! HTTP/REST API mocking library for MockForge.
//!
//! This crate provides HTTP-specific functionality for creating mock REST APIs,
//! including OpenAPI integration, request validation, AI-powered response generation,
//! and management endpoints.
//!
//! ## Overview
//!
//! MockForge HTTP enables you to:
//!
//! - **Serve OpenAPI specs**: Automatically generate mock endpoints from OpenAPI/Swagger
//! - **Validate requests**: Enforce schema validation with configurable modes
//! - **AI-powered responses**: Generate intelligent responses using LLMs
//! - **Management API**: Real-time monitoring, configuration, and control
//! - **Request logging**: Comprehensive HTTP request/response logging
//! - **Metrics collection**: Track performance and usage statistics
//! - **Server-Sent Events**: Stream logs and metrics to clients
//!
//! ## Quick Start
//!
//! ### Basic HTTP Server from OpenAPI
//!
//! ```rust,no_run
//! use axum::Router;
//! use mockforge_core::openapi_routes::ValidationMode;
//! use mockforge_core::ValidationOptions;
//! use mockforge_http::build_router;
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     // Build router from OpenAPI specification
//!     let router = build_router(
//!         Some("./api-spec.json".to_string()),
//!         Some(ValidationOptions {
//!             request_mode: ValidationMode::Enforce,
//!             ..ValidationOptions::default()
//!         }),
//!         None,
//!     ).await;
//!
//!     // Start the server
//!     let addr: std::net::SocketAddr = "0.0.0.0:3000".parse()?;
//!     let listener = tokio::net::TcpListener::bind(addr).await?;
//!     axum::serve(listener, router).await?;
//!
//!     Ok(())
//! }
//! ```
//!
//! ### With Management API
//!
//! Enable real-time monitoring and configuration:
//!
//! ```rust,no_run
//! use mockforge_http::{management_router, ManagementState};
//!
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! let state = ManagementState::new(None, None, 3000);
//!
//! // Build management router
//! let mgmt_router = management_router(state);
//!
//! // Mount under your main router
//! let app = axum::Router::new()
//!     .nest("/__mockforge", mgmt_router);
//! # Ok(())
//! # }
//! ```
//!
//! ### AI-Powered Responses
//!
//! Generate intelligent responses based on request context:
//!
//! ```rust,no_run
//! use mockforge_data::intelligent_mock::{IntelligentMockConfig, ResponseMode};
//! use mockforge_http::{process_response_with_ai, AiResponseConfig};
//! use serde_json::json;
//!
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! let ai_config = AiResponseConfig {
//!     intelligent: Some(
//!         IntelligentMockConfig::new(ResponseMode::Intelligent)
//!             .with_prompt("Generate realistic user data".to_string()),
//!     ),
//!     drift: None,
//! };
//!
//! let response = process_response_with_ai(
//!     Some(json!({"name": "Alice"})),
//!     ai_config
//!         .intelligent
//!         .clone()
//!         .map(serde_json::to_value)
//!         .transpose()?,
//!     ai_config
//!         .drift
//!         .clone()
//!         .map(serde_json::to_value)
//!         .transpose()?,
//! )
//! .await?;
//! # Ok(())
//! # }
//! ```
//!
//! ## Key Features
//!
//! ### OpenAPI Integration
//! - Automatic endpoint generation from specs
//! - Request/response validation
//! - Schema-based mock data generation
//!
//! ### Management & Monitoring
//! - [`management`]: REST API for server control and monitoring
//! - [`management_ws`]: WebSocket API for real-time updates
//! - [`sse`]: Server-Sent Events for log streaming
//! - [`request_logging`]: Comprehensive request/response logging
//! - [`metrics_middleware`]: Performance metrics collection
//!
//! ### Advanced Features
//! - [`ai_handler`]: AI-powered response generation
//! - [`auth`]: Authentication and authorization
//! - [`chain_handlers`]: Multi-step request workflows
//! - [`latency_profiles`]: Configurable latency simulation
//! - [`replay_listing`]: Fixture management
//!
//! ## Middleware
//!
//! MockForge HTTP includes several middleware layers:
//!
//! - **Request Tracing**: [`http_tracing_middleware`] - Distributed tracing integration
//! - **Metrics Collection**: [`metrics_middleware`] - Prometheus-compatible metrics
//! - **Operation Metadata**: [`op_middleware`] - OpenAPI operation tracking
//!
//! ## Management API Endpoints
//!
//! When using the management router, these endpoints are available:
//!
//! - `GET /health` - Health check
//! - `GET /stats` - Server statistics
//! - `GET /logs` - Request logs (SSE stream)
//! - `GET /metrics` - Performance metrics
//! - `GET /fixtures` - List available fixtures
//! - `POST /config/*` - Update configuration
//!
//! ## Examples
//!
//! See the [examples directory](https://github.com/SaaSy-Solutions/mockforge/tree/main/examples)
//! for complete working examples.
