Bump Patronus to 0.35.0

[Nikil-Shyamsunder]

• bumps Patronus to 0.35.0
• this affected relying on 0.34.2 in the graph interpreter and lowering. there were a few places where I was relying on indexing or the length of the underlying expression context that I was able to solve through maintaing a HashSet of DontCares.
• also fixed a few typos in comments.
