CodeRabbit skipped draft PRs ("Draft PRs are not automatically reviewed
by default"), so a change got its first review only once it was marked
ready. The repository had no CodeRabbit YAML, and every run reported
"Configuration used: defaults".
The new file enables reviews.auto_review.drafts. inheritance: true asks
CodeRabbit to take every key the file leaves unset from the parent
levels; today those are plain defaults, so draft review is the only
change. CodeRabbit reads the file from the PR's head branch, so older
feature branches pick it up once they merge main.
