Some freshly cloned VMs still report template/generic hostnames during discovery. Probe DMI product serial over SSH and map it to Terraform VMIDs so cp-2/cp-3/wk-2 can be resolved even before hostname reconciliation.
Increase default SSH timeout, reduce scan concurrency, and add a second slower scan pass to avoid transient misses on busy runners. Also print discovered hostnames to improve failure diagnostics when node-name matching fails.
