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.

+# Prometheus
+
+Prometheus collects metrics from every service on Dankclaw by scraping their `/metrics` endpoints. It feeds the Grafana dashboards. The `node-exporter` containers may add podman/cgroup metrics for full host visibility.
+
+**Host:** Dankclaw — **Hostname:** `prometheus.dankclaw.local` — **Port:** 9090 — **Docs:** https://prometheus.io/docs
+
+## Facts
+
+| Item | Value |
+|------|-------|
+| Image | `docker.io/prom/prometheus:latest` |
+| Port | 9090 (host) → 9090 (container) |
+| Config | `/etc/prometheus/prometheus.yml` (bind mount) |
+| Data volume | TSDB |
+| Retention | `--storage.tsdb.retention.time=30d` |
+
+## prometheus.yml Targets
+
+```yaml
+scrape_configs:
+  - job_name: "prometheus"
+    static_configs:
+      - targets: ["localhost:9090"]
+
+  - job_name: "comfyui"
+    static_configs:
+      - targets: ["comfyui:8188"]
+
+  - job_name: "node"
+    static_configs:
+      - targets: ["node-exporter:9100"]
+```
+
+Allow the `/metrics` endpoint on each service where the exporter exists. For services without a native exporter, use the Prometheus `blackbox` exporter (probe mode) to check up/down and latency.

+## Volumes
+
+| Container path | Host path (convention) |
+|----------------|------------------------|
+| `/etc/prometheus` | `/opt/prometheus/config` |
+| `/prometheus` | `/opt/prometheus/data` |
+
+## Healthcheck
+
+Prometheus responds on `/-/healthy` with 200.
+
+## Gotchas
+
+- Keep scrapes modest for a small homelab; too many targets bloat the TSDB.
+- Use recording rules for heavy queries (see [[Grafana]]).
+- Set a retention policy or the data volume grows without bound.
