Updates to the hashable library require us to implement Eq for Context types, which I've defined as basic environment equality across the contexts. In addition, I had to eliminate a few cases of uni patterns that GHC did not catch before.

Wow, great fix, thank you so much! It seems like it worked on CI right? (The failing tests are because the clang version mismatch iirc?)

Yeah, I think the nix and linux CIs are still failing because of an absent flag for their clang versions.
