//! NIP-09 Deletion Request Disrespector Mode Integration Tests
//!
//! Tests the deletion request disrespector mode behavior:
//! - Disrespector mode accepts deletion events but doesn't process them
//! - No holding database is created in disrespector mode
//! - Normal mode creates holding database and processes deletions
//!
//! # Running Tests
//!
//! ```bash
//! # Run all disrespector tests
//! cargo test --test nip09_disrespector
//!
//! # Run specific test
//! cargo test --test nip09_disrespector test_disrespector_mode_no_holding_database
//!
//! # With output
//! cargo test --test nip09_disrespector -- --nocapture
//! ```
