/**
 * Wraps a schema expression in a library-specific lazy reference when the type
 * is a complex (non-scalar, non-enum) named type, avoiding issues with
 * mutually-recursive input types.
 *
 * Each validation library has its own lazy syntax (z.lazy, v.lazy, etc.), so
 * callers supply the wrapper function.
 *
 * @param visitor - Type lookup used to distinguish scalars/enums from complex types.
 * @param type - GraphQL type node for the schema expression.
 * @param schema - Generated schema expression to wrap when needed.
 * @param lazyWrapper - e.g. `(s) => \`z.lazy(() => ${s})\``
