`smallwebwaf` with no command now prints the commands and exits with status 2. The image runs rproxy, or servewaf with SMALLWEBWAF_COMMAND=servewaf. The passing-on code, its settings and its log fields and metric go. internal/proxy keeps the checks, answers, reports and own endpoints; its tests run through the real rproxy. The documents describe the pair. Judgement call: clients.json keeps token_refused, since state files refuse unknown fields. Deviation: script/gitea-requests sets SWWAF_LOG_REQUEST_HEADERS, to label requests. Partially verified: make example-app and make gitea-requests never built the image, as Ubuntu's snapshot service answered 5xx. Model: opus-5-5

The metrics
What GET /_smallwebwaf/metrics answers with, at servewaf's own address.
"Metrics endpoint" in SPEC.md describes the endpoint. Prometheus
keeps the instance label as exported_instance unless the scrape sets
honor_labels: true. rproxy has no metrics.

When a request is counted
servewaf counts a denied request at its decision, and a request to its own
endpoints when it is answered. It counts an allowed request when its report
comes, with the status, bytes and times the report gives. These are not counted:
- a report itself;
- an allowed request whose report never comes;
- a question refused with
400; - a question whose body stopped arriving.
