1//! Unified CLI error type system
2//!
3//! Design principles:
4//! 1. Clear semantics: each error type has a well-defined use case
5//! 2. No duplication: eliminate semantically overlapping error types
6//! 3. Layered: distinguish system errors vs. business errors
7//! 4. Easy to debug: provide sufficient context information
