fix: Element visible field rejected as required under Zod 4.4

[joshuaboys]

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
