mockforge-http 0.3.102

//! Comprehensive integration test covering major MockForge features
//!
//! This test validates that the main features of MockForge work together:
//! - HTTP server with OpenAPI spec
//! - WebSocket connections
//! - Request validation
//! - Template expansion
//! - Plugin system (basic validation)
