Hi, when generating JSON Schema with z.toJSONSchema, metadata added with .meta() is only included if .meta() is the final method in the chain.

Example where metadata is lost:

const schema = z.object({
  name: z.string().meta({ describe: 'first name' }).min(1)
});

Example where metadata works:

```ts
const schema = z.object({
  name: z.string().min(1).meta({ describe: 'A user name' })
});

Is it expected? feels unintuitive that order matters here

Thanks for taking a look! 🙏
