Now that the cloud-side StreamEnded support has landed, enable it on the
Zed client:
- Send the
`x-zed-client-supports-stream-ended-request-completion-status` header so
cloud knows to send `StreamEnded` status events.
- Track whether `StreamEnded` was received during the stream.
- Emit `StreamEndedUnexpectedly` error when the stream closes without a
`StreamEnded` status, indicating the response was truncated.
Concretely, this means that the agent panel will now display an
abnormally terminated response stream for model calls through a Zed
subscription as an error instead of just stopping.
Release Notes:
- The agent panel now displays an abnormally terminated response stream
for model calls through a Zed subscription as an error instead of just
stopping.
