feat(rn): detach emulators/simulators in dev mode, simplify app verification
In dev mode (non-pure), emulator/simulator processes now: 1. Start the emulator/simulator 2. Wait for readiness probe to pass 3. Exit 0 and detach (emulator stays running as daemon) 4. process-compose marks them as completed In pure mode: keeps existing behavior (foreground, managed by process-compose) App verification simplified: - Use built-in android.sh/ios.sh app status commands - Only check logs for fatal errors (don't try to detect Metro connection) - Fixes "No app ID found" error from incorrect state directory path Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
