<!-- Describe what has changed in this PR --> **What changed?** I renamed all of our Go source code files so that they're snake case instead of camel case. <!-- Tell your future self why have you made these changes --> **Why?** This was an annoying inconsistency we carried over from much older code in the repo. <!-- How have you verified this change? Tested locally? Added a unit test? Checked in staging env? --> **How did you test it?** The renaming process was part of an automated script (https://gist.github.com/MichaelSnowden/47576fffe27aa1cae6b26eaccec7ab55), so it should be consistent. Also, I don't see us doing anything in our codebase that involves parsing our own source files by path: <img width="687" alt="image" src="https://github.com/temporalio/temporal/assets/5942963/c6b873b0-d841-40d1-8b0f-2fe9d8079a53"> *PS: here's a link to the GPT convo I had to generate this renaming script: https://chat.openai.com/share/7f2d011a-a8da-4fa4-9c6d-e09102fdd49f* <!-- Assuming the worst case, what can be broken when deploying this change to production? --> **Potential risks** Mainly merge conflicts, but I used `git mv` so that these are renames instead of deletes/adds, so that shouldn't be a big issue. <!-- Is this PR a hotfix candidate or require that a notification be sent to the broader community? (Yes/No) --> **Is hotfix candidate?** No.
