Central CodeRabbit config for every kleinbem-dev repo.
CodeRabbit reads .coderabbit.yaml from this repo for any repo without its own.
While it exists, the web UI settings don't apply.
A repo that needs something extra adds its own .coderabbit.yaml with
inheritance: true, so it merges on top of this one instead of replacing it.
See central configuration
and inheritance.
CI checks the file against CodeRabbit's schema on every PR.
The kleinbem user account has its own copy in kleinbem/coderabbit.
Keep the two in step.
