//! NIP-01 Compliance Integration Tests
//!
//! These tests verify that ngit-grasp relay implements NIP-01 correctly
//! by using the grasp-audit library to run compliance tests.
//!
//! # Test Strategy
//!
//! - Uses grasp-audit as a library (not CLI)
//! - Automatically manages relay lifecycle
//! - Reuses test specs from grasp-audit (single source of truth)
//! - Pure Rust, no shell scripts
//!
//! # Running Tests
//!
//! ```bash
//! # Run all NIP-01 compliance tests
//! cargo test --test nip01_compliance
//!
//! # Run specific test
//! cargo test --test nip01_compliance test_nip01_smoke
//!
//! # With output
//! cargo test --test nip01_compliance -- --nocapture
//! ```
