Add cadvisor and node-exporter to the Linode chain and miner compose files, exposed publicly on :8080 / :9100 so a separate, external Prometheus (run elsewhere) can scrape them. The validator keeps its own Prometheus from the standard prod stack and is left completely unchanged - it does not scrape the chain or miner. Document the public endpoints and the Cloud Firewall rules that must restrict :8080 + :9100 to the external Prometheus's IP, since cadvisor and node-exporter are unauthenticated.

Add cadvisor and node-exporter to the Linode chain and miner compose files, bound to each machine's VLAN IP (never the public interface), and wire the validator's Prometheus to scrape them over the VLAN via new, gated CHAIN_METRICS_HOST / MINER_METRICS_HOST env vars. When unset (generic prod), the scrape config is byte-identical to before, so only Linode validators pick up the extra chain/miner jobs. Metrics from all three machines then flow through the validator's existing remote-write.
Document the new exporters, the validator .env additions, and the firewall ports (8080 + 9100 inbound on chain/miner from the validator IP).
