initial import: read-only gufo + vLLM dashboard

Single-file FastAPI proxy plus a no-CDN vanilla-JS page for watching a gufo
server and a vLLM server side by side: one Prometheus parser (class Prom) with
per-engine field maps, measured Δcounter/Δt rates for engines that export no
rate gauge, and strict read-only GET-only routing. Engines are opt-in via
*_BASE_URL — unset means no panel, no poll, and a 404 {"configured": false}
without dialling.

Includes the container image and CI so the dashboard can be deployed as an
image rather than a checkout:

- Containerfile: uv-locked two-stage build on python:3.14-slim, non-root
  (uid 10001), binds 8090 (8000 is vLLM's port in this fleet), healthcheck on
  /api/config so a dead engine never marks the dashboard unhealthy. No frontend
  build stage — static/index.html is bundler-free by design and is copied as-is.
- .gitea/workflows/build-and-push.yml: publishes
  gitea.reeseapps.com/Experimental/llm-monitor on main + release tags.

114 tests, no network and no real engines required.
