copilot --remote sessions do not update realtime.

### Describe the bug

when accessing a remote session either via github mobile or in browser, the response is not reflected realtime, the only way to see the response consistently is refreshing the entire page, or relaunching github mobile. It did work sometimes, but it took minutes for the response to show up.

### Affected version

latest

### Steps to reproduce the behavior

start a remote session

### Expected behavior

should see responses immediately

### Additional context

_No response_

Start by reproducing the issue from the reported entry point: start a remote session and observe it in GitHub mobile or a browser without refreshing. Compare when responses appear immediately versus after refreshing or relaunching the app; done means remote-session responses are consistently visible in realtime across those clients.
