 * Validates the checksum of a module file against a stored value in the checksum database.

 * @param sums - The checksum database to retrieve and register checksums.
 * @param tmp - The URI of the temporary file to validate.
 * @param ctx - The module context for registration.
 * @param target - The module target identifier.
 * @param version - The semantic version of the module.
 * @returns A promise resolving to a Result indicating success or an error message if validation fails.
