//! Authentication Factory Module
//!
//! This module provides factory functions for creating authentication components.
//! It acts as the central point for instantiating authentication strategies, providers,
//! evaluators, and metadata managers.
//!
//! # Design Principles
//!
//! - **Factory Pattern**: Centralized creation logic for auth components
//! - **SPI-like Design**: Configurable strategies and providers via AuthConfig
//! - **Caching**: Singleton instances cached by config name for efficiency
//! - **Thread-safe**: All factory methods are safe for concurrent use
