feat(pm): H58 — a queued card whose own headings declare it a ruling

`pm:queue` carries two incompatible meanings — "triaged and registered"
and "ready for a dev" — and the card-selection total order reads the
second. Three seats measured cards graded into the pool that were
rulings or records; the price of one instance is a dev round.

Adds one report-only row to the half-state patrol. It matches a frozen,
heading-anchored marker set, each anchor beside the live card it was
measured on, over the `pm:queue` label page the sweep already lists,
reading the comment thread only where another row already bought it.
Exit codes unchanged; nothing blocked; no label written.

The remedy names the four states that already exist — `tracking`,
`needs-user-decision`, closed, or a corrected `pm:queue` — because every
measured instance resolved into one of them. No fifth state is proposed.

Two Zone-2 readings moved the anchor set: "Both are dispositions" is
PROSE on the card it was measured on, not a heading, so it is recorded
and refused; and both handover cards carry the heading "Two rulings of
mine you may want to overturn", which is the spelling pinned in its
place.
