/**
 * Validate that all packages use strong integrity hashes (SHA512).
 * Weak hash algorithms like SHA1 and SHA256 are more susceptible to
 * collision attacks, potentially allowing attackers to substitute
 * malicious packages that match the same hash.
 *
 * Options:
 * - requiredAlgorithm: The minimum required hash algorithm (default: 'sha512')
 * - exclude: Array of package names to exclude from validation
 *
 * Example config:
 * ```ts
 * pluginRules: {
 *   'lockfile/validate-integrity': ['error', { requiredAlgorithm: 'sha512', exclude: [] }]
 * }
 * ```
