//! Unified CLI error types with user-friendly formatting
//!
//! This module defines all error types used by the Paladin CLI,
//! with Display implementations that provide helpful error messages.
//!
//! # Error Categories
//!
//! - **Validation errors**: Invalid config, missing fields
//! - **Execution errors**: LLM failures, timeout, stop words
//! - **I/O errors**: File not found, permission denied
//! - **User interaction**: Cancelled operations
