Provide full model syntax for queries

[leo]

This change ensures that schema queries can make use of the same syntax that is used for defining the database schema in code, with exactly the same syntax helpers as well:

import { create } from 'ronin';
import { string } from 'ronin/schema';

await create.model({
  slug: 'account',
  fields: {
    handle: string().required()
  }
});
