feat(linkedin-studio): N3.5 — MR-F8 build-html-forsoning (blockquote+lenker+FIGUR->SVG port + paritetstest) [skip-docs]

Plugin eier hele render/ (KTG-go 16.07, eierskapsvalg a). Portet fra
maskinrommets tools/build-html.mjs (read-only): flerlinjers blockquote
(avsnitt i quote), [tekst](url)-lenker med http/https/mailto-whitelist,
FIGUR-markoer -> inline SVG med figcaption + fallback til blockquote.
CSS for de tre konstruktene. 7 nye paritetstester (repoets testtilfeller
kopiert + med-SVG-case); paritetsbevis: samme fixture gjennom begge
motorer = byte-identisk parser-HTML. Render-floor 53 -> 60.
