getAllFeatureFlags() returns cached flags synchronously

1.38.0

Minor Changes

• #3977 6200888 Thanks @turnipdabeets! - Add getAllFeatureFlags(), which returns all currently loaded feature flags as structured FeatureFlagResults (key, enabled, variant, payload). It is a synchronous read of the cached flags and does not send a $feature_flag_called event. (2026-06-26)
