Move detailed diagnostic messages (SSH key paths, secrets scope, remote user/port, job submission details, upload progress) from cmdio.LogString to log.Infof so they only appear with --log-level=info. Add spinners for long-running operations: binary upload, cluster state check, job startup wait, and metadata polling. Keep concise user-facing step messages (Connecting, Uploading, Starting, Connected) for progress visibility. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Good change. Moving diagnostic messages from cmdio.LogString to log.Infof and adding spinners for long-running operations improves the user experience. One nit on inconsistent spinner cleanup pattern.

[Agent Swarm Review] [Nit]
The spinner for binary upload creates and closes inline rather than using defer sp.Close(). An early return between sp := cmdio.NewSpinner(ctx) and sp.Close() would leak the spinner. The other spinners in this PR correctly use defer sp.Close().
Suggestion: Move sp.Close() to a defer and remove the explicit close calls.

Job run ID can be very useful for debugging (and cluster id too actually)
And the problem is that we can't really get them after the fact (unless we also store local logs to a file, which we don't do right now)
