fix: Element visible field rejected as required under Zod 4.4

Hey I'm running into a validation failure after bumping zod 4.3.6 → 4.4.3 in our app.

Using @json-render/react@0.18.0 (also checked 0.19.0 on npm, same behaviour, and this is what made me notice the github release mismatch).

The visible field on elements is now being treated as required

  import { z } from 'zod';
  import { schema } from '@json-render/react';

  const catalog = schema.createCatalog({
    components: {
      Stack: { props: z.object({}), description: 'box', example: {} },
    },
    actions: {},
  });

  const result = catalog.validate({
    root: 'main',
    elements: {
      main: { type: 'Stack', props: {}, children: [] },
    },
  });

console.log(result);
  // {
  //   success: false,
  //   error: ZodError: [
  //     {
  //       code: 'invalid_type',
  //       expected: 'nonoptional',
  //       path: [ 'elements', 'main', 'visible' ],
  //       message: 'Invalid input: expected nonoptional, received undefined'
  //     }
  //   ]
  // }

On zod 4.3.6 the same call succeeds. Not sure if this is a zod 4.4 compatibility thing or something on our end.

Versions:

• @json-render/core@0.18.0, @json-render/react@0.18.0, @json-render/shadcn@0.18.0, (about to install @json-render/react-email@0.18.0)
• zod@4.4.3 (any 4.4.x reproduces)
• Node 24, pnpm 10

Happy to dig in further if useful

Reproduce the report using schema.createCatalog and catalog.validate with the supplied TypeScript example, comparing Zod 4.3.6 with 4.4.x. Trace the schema used for elements and visible from those entry points; done means the same catalog input validates successfully on Zod 4.4.x without making visible required.
