Amends ci.monitor-armed-at-pr-open (prose + Signals only; heading and key
unchanged, no supersession) with the monitor-classification rules that were
missing.

Landing #436/#583 today, my CI monitor filtered per-context statuses on
`!= "success"` and announced "NOT all green" on two fully green PRs, because
`Build & push image (amd64)` reports `skipped`. Nothing was blocked — Gitea's
combined /status already treats skipped as non-blocking and reported
overall=success — but a false red costs a diagnosis cycle every time.

Two corrections recorded:
- The image job is skipped on EVERY PR (job-level `if: github.event_name !=
  'pull_request'`; images build only on push-to-main and tags), NOT because of
  the docs-only mechanism. Misattributing it to docs-only is a plausible-sounding
  wrong diagnosis, since docs-only gates STEPS precisely so required jobs still
  report success. decisions.md already stated the fact from the branch-protection
  angle; the monitor-authoring consequence was missing.
- skipped / failure / cancelled are three distinct meanings and must not be
  collapsed. Prefer gating on the combined `.state`.

The documented filter is verified in BOTH directions: silent on a green PR
carrying a skipped build, and still dirty on a genuinely pending run. My first
draft of it was itself broken — `select(.status != …)` after the pipeline had
renamed `.status` to `.st`, so it compared against null and reported a green PR
as nine failures. That failure is recorded in the note, per the "verify your
detector" rule.

fixes #592
