//! CLI arguments for task relationship commands.
//!
//! Responsibilities:
//! - Define Args structs for clone, split, children, parent, relate, blocks, and mark-duplicate commands.
//! - Define TaskRelationFormat enum for output formatting.
//!
//! Not handled here:
//! - Command execution (see clone, split, children, parent, and relations handlers).
//!
//! Invariants/assumptions:
//! - All types must be Clone where needed for clap.
