 * Clear nauth auth cookies on the response.
 *
 * - Clears access token, refresh token, CSRF token cookies
 * - Optionally clears device token cookie (only when forgetDevice=true)
 * - Device token cookies persist across logout by default (remember device feature)
 * - Applies security attributes consistent with how cookies were set
 * - Uses configured cookie name prefix (default: 'nauth_')
 *
 * @param res - HTTP response object (Express or Fastify compatible)
 * @param config - NAuth configuration (optional, for cookie name resolution)
 * @param opt - Optional cookie options to match configured attributes
 * @param forgetDevice - If true, also clears device token cookie (for "forget me" logout). Default: false
