Closes #656

ValidationErrorwas exported butinstanceof ValidationErrorchecks failed after TypeScript transpilation because the prototype chain was not restored.Fix
Added
Object.setPrototypeOf(this, new.target.prototype)in the constructor so callers can reliably useinstanceof ValidationErrorfor typed error handling.
