Storage Metrics in danube-cli
The danube CLI gains trend / top / health subcommands under storage buckets metrics, plus extended snapshot view.
What's changed
- danube storage buckets metrics <id>: extended with error rate, p50/p95 latency, ingress bytes, and a freshness badge
- danube storage buckets metrics trend <id>: time-series view with sparkline (default), table, CSV, and JSON output formats
- danube storage buckets metrics top <id> --by size|egress|requests: top-N objects in a bucket
- danube storage buckets metrics health <id>: pending multipart uploads, deleted-version size, last health-check time
- Exit code 3 on stale data so scripts and agents can branch on freshness
