Review progress now uses GitHub check runs by default

Review Progress Reports

CodeRabbit now publishes its canonical, user-facing review status and progress through GitHub progress reports and check runs by default, so you can follow a review's status without relying on commit statuses.

If your required checks or automations depend on the legacy commit status, enable reviews.commit_status; it applies only while reviews.review_progress is disabled. reviews.fail_commit_status still controls failure reporting, applying to whichever status surface is active.

See the configuration reference for details.
