network: retire Slate AX; add SODOLA switch migration plan and network topology doc
- infrastructure/network.md: permanent topology reference — VLAN 1 (main LAN)
+ VLAN 10 (homelab 192.168.8.0/24), Fritz!Box 7590 as VLAN router,
SODOLA 5-Port 2.5Gbit as homelab switch
- plans/2026-06-01-slate-ax-to-sodola-migration.md: full migration runbook
(pre-flight, Fritz!Box second-network config, SODOLA VLAN table, cutover
procedure, verification commands). Gateway 192.168.8.1 is unchanged —
no LXC/VM config edits needed. Fritz!Box DHCP for VLAN 10 hands out
192.168.8.2 (Technitium CT 107) as DNS, closing the outstanding item in dns.md.
- plans/index.md: establishes plans/ convention (Planned → In Progress → Done)
- CONTRIBUTING.md: plan page template + linking discipline for plans
