Currently, our makefile will run buf generate even when the files in the api directory are unchanged. This PR prevents buf generate from running when nothing has changed by leveraging a rust build.rs and cargo's rerun hints.
The benefit is that for local development, crates that depend on the output of buf generate will have a better chance of caching their builds.
The drawback is that if someone alters the generated files, buf generate won't run to revert the changes. They would need to run make clean first.
