Presentation host coalescing buckets agent rows by short hostname and
PVE node names are short, so a pve01 in one estate merged with a pve01
in another, re-parenting both estates workloads onto one row and
cross-wiring reachability. Veto the merge when the rows carry proof of
distinct machines, a disjoint machine ID set, differing DMI UUIDs, or
differing Proxmox cluster names, while equal cluster names still merge
so the same cluster added under two connections keeps its single row.
Apply the same cluster discrimination to agent-node link inference,
whose short endpoint alias keys and short-hostname corroboration
fallback could hand one estate agent to the other estate node.
