Follow-up to #77653: textWithoutReferenceLines built a fresh /g RegExp per call and hand-managed lastIndex — but it runs on both sides of every message comparison in the reconcile loops. An anchored non-global regex has no shared-lastIndex hazard and can be hoisted to module scope. Also removes textWithoutImageRefs, whose last production consumer #77653 replaced (kept IMAGE_REF_LINE_RE for extractImageRefs), and retargets its now-stale comment.
