Admin-enforced inheritance overrides per-repo settings

Enforce configuration inheritance org-wide

Administrators can now enforce across an entire organization or workspace by setting inheritance: true in a global override. The override's inheritance flag is evaluated before the inheritance walk and takes precedence over each configuration level's own flag, so every repository and PR review merges the full inheritance chain — including repositories that set inheritance: false (or omit it) in their own .coderabbit.yaml or UI settings. Turn on inheritance everywhere from one place instead of editing every configuration source.

See Enforcing inheritance for details.
