{κ : Cardinal.{w}} → CategoryTheory.IsCardinalFiltered.exists_cardinal_directed.Diagram J κ → J → Type wGiven a κ-bounded diagram D in a category J, an object e : J
is terminal if 𝟙 e belongs to D and for any object j of D,
there is a unique morphism j ⟶ e in D, such that these unique morphisms
are compatible with precomposition with morphisms in D.
