With SwiftUICore resolved (prev commit), the app link surfaced the real blocker:
`Undefined symbols: _OBJC_CLASS_$_RCTRootContentView`, referenced from
react-native-ios-utilities (RCTView+Helpers.o). RCTRootContentView is a legacy
paper class that the prebuilt new-architecture React in RN 0.85 no longer exports.
ios-utilities@5.2.0 is the latest release and still references it, so no version
bump fixes this.
Patch the single offending helper (closestParentReactContentView) to return nil
with an RCTView? type, dropping the only RCTRootContentView reference in the pod.
It feeds only the last-resort touch-handler fallback, moot under the new arch.
Nothing else (incl. react-native-ios-context-menu) references it.
NOTE: react-native-ios-utilities + react-native-ios-context-menu (both Dominic's,
latest 5.2.0 / 3.2.1) are effectively unmaintained for RN 0.85 — candidates for
removal/replacement (context-menu is used only in DiscoverFilters.tsx), like udp.
