Records the decision to replace the cluster-resident control VM with a
dedicated always-on physical mini-PC (ubongo) outside the Proxmox
cluster, collapsing control plane, AI-worker host, dev home, and local
test runner into one box. Basis for ADR-015.

Brainstormed design for docs/hardware/reference.md (physical compute +
network gear + workload placement intent), a stdlib-only capacity-scan.py,
and an on-demand /capacity-review skill that reports to docs/hardware/reviews/.
Mirrors the repo-scan -> /review-repo -> docs/reviews triad.
TODO additions: schedule /capacity-review later and decide its usage-stats
source (Proxmox RRD vs the Prometheus/Loki/Grafana/Alloy stack) before
building any hook (8.4); reevaluate the stdlib-only script policy (#14).
