[Bug]: outputSchema cannot describe infinite nested structures using `z.lazy()`

[FireTable]

Describe the bug

example code

  const BaseNodeSchema = z.object({
    id: z.string().describe('node id'),
    title: z.string().describe('node title'),
    description: z.string().describe('node description'),
    templateId: z.string().optional().describe('node template id'),
  });

  const NodeSchemaWithNodes: z.ZodType<any> = z.lazy(() =>
    BaseNodeSchema.extend({
      nodes: z.array(NodeSchemaWithNodes).describe('child nodes').optional().nullable(),
    })
  );

  console.warn(
    'validate result zod schema',
    NodeSchemaWithNodes.parse({
      id: '1',
      title: '1',
      description: '1',
      templateId: '1',
      nodes: [
        {
          id: '2',
          title: '2',
          description: '2',
          templateId: '2',
          nodes: [
            {
              id: '3',
              title: '3',
              description: '3',
            },
          ],
        },
      ],
    })
  );

run result

// success validate

  id: "1",
  title: "1",

  templateId: "1",

    {
      id: "2",

          description: "3",
        }
      ],
    }
  ],
}
