) Summary: ### Context This is a follow-up to D86201689 following user feedback on `0.83.0-rc.2`: react-native-community/discussions-and-proposals#954 (reply in thread). The problem was that we were incorrectly attributing any and all `IInspector::addPage()` calls to represent a new React Native Host being registered. However, this API also remains common to the legacy Hermes `ConnectionDemux` runtime target setup (which does not represent a host target). ### This diff We now fork this code path internally based on `InspectorTargetCapabilities.prefersFuseboxFrontend`, in order to track `registeredHostsCount` accurately (i.e. **only** for HostTarget page registrations). Changelog: [General][Fixed] - React Native DevTools: Fix a bug where we would incorrectly flag apps using additonal Hermes runtimes (e.g. Reanimated) as being multi-host Reviewed By: hoxyq Differential Revision: D88386623
