 * Implementation of an interactive authentication provider for the Fusion MSAL Node module.

 * This implementation is intended for scenarios where interactive login is required, such as CLI tools or development utilities.
 *
 * Developers extending this provider can customize the interactive flow, server handling, or PKCE logic as needed.
 * Ensure that any changes remain consistent with the expected interface and security best practices.
