//! Command implementation layer.
//!
//! Purpose:
//! - Centralize "do the work" command implementations separate from the CLI surface (`crate::cli`).
//! - Mirror the CLI structure for easier navigation and maintenance.
//!
//! Non-goals:
//! - This module does not define clap argument parsing; see `crate::cli` for that.
// Re-export commonly used doctor types for convenience
