integration tests appear to be missing

The documentation states that integration tests exist:

https://github.com/anthropics/claudes-c-compiler/tree/6f1b99acb2f4ec2414592136c2009fe7713deec3?tab=readme-ov-file#testing

but no such folder appears in the repo as of the lastest commit (nor does it appear elsewhere in the repository):

https://github.com/anthropics/claudes-c-compiler/tree/6f1b99acb2f4ec2414592136c2009fe7713deec3

This makes it harder to verify the efficacy of the compiler.
