The em-dash-overuse text analyzer ran stripHtmlToText over raw markup,
which drops tags but leaves character entities intact. A model that wrote
—, —, or — rendered a real em-dash the counter never
saw, so 12 entity-escaped dashes on a live page slipped through.
Decode the em-dash entities (named, zero-padded decimal, upper/lower hex)
to the literal glyph before counting. En-dash entities stay untouched: the
rule counts em-dashes, and the literal en-dash was never counted either.
The gap lived only in the regex / static-HTML path (detectText and
detect-html's runTextContentAnalyzers, both over raw HTML). The browser
adapter never ran this analyzer, so build:browser and build:extension
produce no diff.
