 In this file, we prove that sheafification is compatible with functors which
 preserve the correct limits and colimits.

chore: remove terminal, terminal refines (#10762)

I replaced a few "terminal" refine/refine's with exact.

The strategy was very simple-minded: essentially any refine whose following line had smaller indentation got replaced by exact and then I cleaned up the mess.

This PR certainly leaves some further terminal refines, but maybe the current change is beneficial.

refactor(CategoryTheory/Sites): sheafification as an abstract left adjoint (#9012)

We define a typeclass HasSheafify which says that presheaves on a site with values in some category can be sheafified, i.e. that the inclusion functor from sheaves to presheaves has a left exact left adjoint. We redefine presheafToSheaf as an arbitrary choice of such a left adjoint.

feat(CategoryTheory): a version of sheafCompose for functors preserving smaller limits (#8235)

Introduces a new typeclass GrothendieckTopology.HasSheafCompose F which says that a sheaf postcomposed with the functor F is still a sheaf. The previous API proved that a functor preserving certain limits has this property, this PR also adds a proof that a functor preserving limits of a smaller size has this property.
