//! Network Security Tests
//!
//! Tests for HTTP-related security threats documented in specs/006-threat-model.md
//! Section 5.3: HTTP Attack Vectors
//!
//! These tests verify:
//! - URL allowlist enforcement
//! - Response size limits
//! - Timeout handling
//! - Redirect security
//! - curl/wget builtin security
//!
//! Run with: `cargo test --features http_client network_security`
