`query.from_not_entity`

Query reads something that is not an entity.

Area 6, Reads and writes; not declinable; the next step is usually the agent's.

example

type Title = Text {    max_length: 80}entity Book {    id: Uuid    title: Title    subtitle: Title?    available: Bool}query titles(title: Book.title) -> List<Book> {    from: Title    order: [Book.id asc]    limit: 20}

error from: names Title, which isn't an entity

--> main.jadpo:13:11

   |13 |     from: Title   |           ^^^^^ not an entity

reason: Title is a type; a query reads stored records, so from: names an entity declared in the domain's entities/ folder.
next: Name the entity the query reads (agent)
