Frank 5829a0bfe8 docs: rename docs/ -> serverAppConfigs-docs/ per system-wide PROJECTNAME-docs convention

All in-repo path references (AGENTS.md, README, old scripts, report artifacts,
test code paths) rewritten in the same commit; focused-test map extended for
.gitignore, old/scripts/*, dankclaw/comfyui/*, and report/* per this repo's
own convention ('add one before committing'). Obsidian wikilinks are
title-based and unaffected.

Node-Exporter

Node-Exporter exposes host metrics (CPU, RAM, disk, network) to Prometheus. One instance runs per host inside its own container.

Hosts: Dankserver + Dankclaw — Docs: https://prometheus.io/docs/guides/node-exporter

Facts (from research)

Item	Value
Image	`prom/node-exporter:latest`
Port	9100 (host)
Network	`host` mode
Config	`--path.procfs=/host/proc`, `--path.sysfs=/host/sys`, `--path.rootfs=/rootfs`

Configuration

services:
  node-exporter:
    image: prom/node-exporter:latest
    restart: always
    network_mode: host
    pid: host
    volumes:
      - /proc:/host/proc:ro
      - /sys:/host/sys:ro
      - /:/rootfs:ro
    command:
      - --path.procfs=/host/proc
      - --path.sysfs=/host/sys
      - --path.rootfs=/rootfs

Prometheus Targets

Prometheus scrapes each host's node-exporter directly:

Host	Target
Dankserver	`192.168.0.235:9100`
Dankclaw	`192.168.0.143:9100`

These scrape jobs live in the Prometheus config; see Prometheus and Observability.

Gotchas

Requires network_mode: host (or a published port) so Prometheus can reach 9100.
The /proc, /sys, and root mounts must be read-only (:ro).
Do not mount the same paths on both hosts' containers; each node-exporter reflects only its own host.
