/**
 * Resolves configuration from multiple sources with consistent behavior.
 *
 * ConfigResolver is the preferred high-level API for loading B2C configuration.
 * It provides:
 * - Consistent hostname mismatch protection across SDK and CLI
 * - Extensibility via the ConfigSource interface
 * - Convenience methods for creating B2CInstance and auth credentials
 *
 * ## Resolution Priority
 *
 * Configuration is resolved with the following precedence (highest to lowest):
 * 1. Explicit overrides (passed to resolve methods)
 * 2. Sources in order (dw.json, ~/.mobify by default)
 *
 * ## Usage
 *
 * ```typescript
 * import { createConfigResolver } from '@salesforce/b2c-tooling-sdk/config';
 *
 * const resolver = createConfigResolver();
 *
 * // Simple resolution
 * const { config, warnings } = resolver.resolve({
 *   hostname: process.env.SFCC_SERVER,
 *   clientId: process.env.SFCC_CLIENT_ID,
 * });
 *
 * // Create B2CInstance directly
 * const instance = resolver.createInstance({ hostname: '...' });
 *
 * // Get auth credentials for use with resolveAuthStrategy
 * const credentials = resolver.createAuthCredentials({ clientId: '...' });
 * ```
 *
 * ## Custom Sources
 *
 * You can provide custom configuration sources:
 *
 * ```typescript
 * import { ConfigResolver } from '@salesforce/b2c-tooling-sdk/config';
 *
 * class MySource implements ConfigSource {
 *   name = 'my-source';
 *   load(options) { return { hostname: 'custom.example.com' }; }
 * }
 *
 * const resolver = new ConfigResolver([new MySource()]);
 * ```

     * @param sources - Custom configuration sources. If not provided, uses default sources (dw.json, ~/.mobify, package.json).
     *                  Sources are automatically sorted by priority (lower number = higher priority).
