Research direction

Start by running the reported ns run --device ... command and compare its output and keyboard behavior with --no-hmr; inspect the project's package.json and src/main.ts entry point. Done means the app and HMR launch once on an iOS device and TextField or SearchBar reliably opens the keyboard with HMR enabled.
