infra-standards: infrastructure-standards skill documents retired 3-digit VMID ranges

[JacobPEvans-personal]

The skill's 'VMID & IP Addressing' table still presents the legacy flat 3-digit ranges (100-109 infrastructure, etc.) as the active scheme. The homelab has moved to the 6-7-digit tier-positional VMID scheme (tofu-proxmox docs/INFRASTRUCTURE_NUMBERING.md; canonical: docs.jacobpevans.com/infrastructure/vmid-network-tiers). The stale table actively misleads agents into assigning new 3-digit IDs. Rewrite the section to describe the positional scheme (and the crit-1 static-IP exception), or link out to the canonical page instead of embedding ranges.

Scope note from the incident that triggered this: the rewrite should not re-embed range tables at all — it must match/link the canonical docs-starlight page (docs.jacobpevans.com/infrastructure/vmid-network-tiers), which owns the digit-by-digit allocation. Embedded copies are what go stale.
