1//! CLI argument reducer module.
2//!
3//! This module implements a reducer-based architecture for processing CLI arguments,
4//! following the same patterns as the pipeline reducer in `crate::reducer`.
5//!
6//! # Architecture
7//!
8//! ```text
9//! Args (clap) → args_to_events() → [CliEvent] → reduce() → CliState → apply_to_config() → Config
10//! ```
11//!
12//! ## Benefits
13//!
14//! - **Testable**: Pure reducer function is easy to unit test
15//! - **Maintainable**: Adding new CLI args = add event + reducer case
16//! - **Consistent**: Matches existing pipeline reducer architecture
17//! - **Traceable**: Event sequence can be logged/debugged
18//!
19//! # Example
20//!
21//! ```ignore
22//! use crate::cli::reducer::{args_to_events, reduce, CliState, apply_cli_state_to_config};
23//!
24//! let events = args_to_events(&args);
25//! let mut state = CliState::initial();
26//! for event in events {
27//!     state = reduce(state, event);
28//! }
29//! apply_cli_state_to_config(&state, &mut config);
30//! ```
