Declarative validators (zod, yup, etc)

https://github.com/jquense/yup

class User extends YupEntity(
  object({
    name: string().required(),
    lastName: string().required(),
    age: number().required().positive().integer(),
    email: string().email(),
    website: string().url().nullable(),
    createdOn: date().default(() => new Date()),
  })) {

  pk() {return this.id}

  get fullName() {
    return `${this.name} ${this.lastName}`;
  }
}

Use the lifecycle integration of Entity.validate

Perhaps we should provide an abstract interface, so any third-party validator could be hooked up in the same way. If their APIs are too different, we could simply ship adapters as well
