//! # Address Book Command
//!
//! This module implements the `scope address-book` command for managing
//! watched addresses and viewing aggregated address book data.
//!
//! ## Usage
//!
//! ```bash
//! # Add an address to address book
//! scope address-book add 0x742d... --label "Main Wallet"
//!
//! # List watched addresses
//! scope address-book list
//!
//! # Remove an address
//! scope address-book remove 0x742d...
//!
//! # View address book summary
//! scope address-book summary
//! ```
