/**
 * Validates if a RENAVAM (Registro Nacional de Veículos Automotores) is valid.
 *
 * RENAVAM can be in two formats:
 * - Old format: 9 digits (will be padded to 11 with zeros)
 * - New format: 11 digits
 *
 * The validation uses a checksum algorithm based on modulo 11.
 *
 * Spaces, dots and hyphens are ignored, so every punctuated form of a RENAVAM is accepted, but
 * any other character, a letter in particular, makes the value invalid. A registration whose
 * digits are all the same (`"00000000000"`) is rejected as well, matching both references below.
 *
 * @param {string} renavam - The RENAVAM value to be validated.
 * @returns {boolean} True if the RENAVAM is valid, false otherwise.
 *
 * @example
 * ```typescript
 * isValidRenavam("639884962"); // true (9 digits, old format)
 * isValidRenavam("00639884962"); // true (11 digits, new format)
 * isValidRenavam("0063988.4962"); // true (dots and hyphens are ignored)
 * isValidRenavam("12345678901"); // false (invalid checksum)
 * isValidRenavam("00000000000"); // false (repeated digits)
 * isValidRenavam("ab00639884962"); // false (invalid format)
 * ```
 *
 * The Código de Trânsito Brasileiro creates the RENAVAM registry but does not define its check
 * digit, so the algorithm below follows the two community references cited as `Based on:`.
