foldkit-entity: the domain

Term	What it is
Entity	A named record type with an `id`, declared once with `Entity.define`, and read by Remote, the Drizzle binding and forms. The package
Relation	A field that refers to another Entity (`Relation.one`, `Relation.many`), stored as a ref key such as `'User:u1'`, never a copy.
Selection	Exactly which fields of an Entity, and through which relations, a consumer needs; it decodes to that shape. `Entity.select`.
Query body	What a query means, as a value: `Query.define(name, Input, ({ input }) => …)` with `Expr` predicates and an order. Compiled to SQL on a server, run over rows by `evaluate`.
