> [!NOTE]
> **Low Risk**
> Single CI orb version bump with no app or pipeline structure changes;
risk is limited to possible orb behavior differences in shared SDK CI
jobs.
> 
> **Overview**
> Bumps the shared CircleCI **`revenuecat/sdks-common-config`** orb from
**4.5.1** to **4.6.0** in `.circleci/config.yml`.
> 
> No workflow or job definitions change—only the orb version. Pipelines
still use the same `revenuecat/*` commands (gem/mise setup, Danger,
release tagging, dependency bumps, etc.) against the newer orb release.
