Research direction

Reproduce the issue in the linked react-navigation example with React Native 0.85.3: run npm run android, press j, and confirm that the debugger is empty. Compare this behavior with a working React Native version or setup, then verify that React Native DevTools displays its expected content on Windows 11 with Hermes and the new architecture enabled.
