mrcharles 0a8865de38 docs: full documentation suite — network, storage, hosts, VMs 
Four new standalone reference documents with Mermaid diagrams (renderable
on Gitea), built from live ground-truth data gathered 2026-07-30:

- NETWORK-TOPOLOGY.md: physical topology diagram, complete switch port
  maps (core-sw01 + tor3-stor), VLAN/subnet tables, cross-rack trunk
  analysis with Mermaid, NFS data-flow diagram, per-host NIC reference
- STORAGE-ARCHITECTURE.md: tier definitions, all 14 physical disks
  inventoried with SMART/size/tier, NFS export→mount map with Mermaid,
  per-spindle VM placement (IOPS hotspot analysis), capacity summary
- HOST-REFERENCE.md: one-page-per-host for all 7 nodes with hardware,
  network config, storage, tuning state, role, and running VMs
- VM-INVENTORY.md: VM placement diagram, all 28 running VMs with
  disk/CPU/RAM/config details, optimization audit (cache mode, CPU type,
  qga, disk controller, k8s wnode sizing), stopped VM reference

Updated docmap.md with all four new entries.
