/**
 * Validates if a CBO (Classificação Brasileira de Ocupações) code exists in the official
 * CBO 2002 table.
 *
 * A string is only read as a code when it is written in one of the documented forms: the 6
 * digits, or the `NNNN-NN` mask, with a single separator between the groups and optional
 * surrounding whitespace. A number is only read as a code when it is a non-negative safe
 * integer.
 *
 * A CBO code is always 6 digits and its leading zeros are part of it, so a value written as
 * bare digits is left padded with zeros to 6 whether it comes as a string or as a number:
 * `10205`, `"10205"` and `"010205"` are the same code.
 *
 * @param {string|number} value - The CBO code to be validated, with or without the hyphen
 * mask, e.g. `"2124-05"`, `"212405"` or `212405`.
 * @returns {boolean} True when the code is a known 6 digit occupation code, false otherwise.
 *
 * @example
 * ```typescript
 * isValidCbo("2124-05"); // true
 * isValidCbo("212405"); // true
 * isValidCbo(212405); // true
 * isValidCbo(10205); // true (padded to 6 digits, so this is "010205")
 * isValidCbo("10205"); // true (padded to 6 digits, so this is "010205")
 * isValidCbo("999999"); // false
 * isValidCbo("2124abc05"); // false (not a documented form)
 * isValidCbo(-212405); // false (not a non-negative safe integer)
 * ```
 *
 * @see Official: https://www.gov.br/trabalho-e-emprego/pt-br/assuntos/cbo/servicos/downloads/cbo2002-ocupacao.csv

 * Community mirror of the same table, the fallback `CBO_TITLES` was built from before the
