remote client exited before becoming ready

Error message

remote client exited before becoming ready

What it means

In RemoteClient::new: wait_for_remote_started completed with Ok(None), meaning the remote server process exited (its IO task finished) before it signalled readiness. The error string is then enriched with the observed exit status.

Solutions

1. Check the appended exit status/stderr for why the remote binary exited
2. Verify the remote server binary is compatible with the host
3. Retry the connection after fixing the environment
