/**
 * ConfigManager — class-based wrapper around the CLI config functions.
 *
 * Provides a single object that encapsulates config directory resolution,
 * file loading/saving, provider preset management, normalization, auditing,
 * and env loading. The underlying implementations live in `config.ts`;
 * this class delegates to them, giving callers a clean interface boundary
 * instead of importing 59+ standalone functions.
