 * Formats a Brazilian CNH (Carteira Nacional de Habilitação) number.
 *
 * @param {string|number} value - The CNH number to be formatted.
 * @param {FormatCnhOptions} [options] - Optional options.
 * @param {boolean} [options.pad] - Whether to pad the value with leading zeros.
 * @returns {string} The formatted CNH, or an empty string when there is nothing to format.
 *
 * @example
 * ```typescript
 * formatCnh("12345678900"); // "123456789-00"
 * formatCnh("8900", { pad: true }); // "000000089-00"
 * ```
 *
 * Resolução CONTRAN nº 886/2021, art. 4º I, defines the CNH registry number as 9 characters plus
 * 2 security check digits, which is the layout this mask reproduces; no official text publishes
 * the check-digit weights used to compute them.
