//! Example: Network Interception (Feature 7)
//!
//! Demonstrates: Intercepting and mocking HTTP requests
//!
//! Run with: `cargo run --example network_intercept`
//!
//! Toyota Way: Poka-Yoke (Mistake-Proofing) - Type-safe request handling
//!
//! PMAT-006: Added abort functionality and wait_for_response
