## Summary
- Buffer stdout/stderr messages from child processes and flush them
every 100ms as a single batched IPC event (`app:output-batch`), reducing
IPC traffic, array allocations, and React re-renders when apps emit
high-volume logs
- Keep `input-requested` messages on the immediate `app:output` channel
for responsive UX
- Renderer processes batched events with a single `setConsoleEntries`
state update instead of one per message

## Test plan
- [ ] Run an app that emits high-volume logs (e.g., `console.log` in a
loop) and verify the UI remains responsive
- [ ] Verify app console still shows all log output correctly
- [ ] Verify interactive prompts (y/n) still appear immediately
- [ ] Verify proxy URL detection and preview panel still work
- [ ] Verify HMR updates still trigger iframe refresh
