Not sure if any code can be abstracted out of `CheckRun` to be shared here. At least the logic for extracting the version from `.jcheck/conf` should be possible to share between CheckRun and CSRCommand. Maybe it belongs in `CheckablePullRequest` now?

I was thinking that perform merge every time maybe not very efficient. But CSR commands might not be used very frequently. I would follow your advice. Thanks!
