feat(art): replace all 72 posts' artwork with the v2 pipeline

Every post now carries one unique local-ComfyUI/Ideogram 4 base frame, composited into EN + ZH share cards, a banner and list thumbs. - the shipped prompts_catalog held only 21 distinct metaphors for 72 posts (16 shared one visual), so all 72 were rewritten as unique object+state metaphors and 10 frames re-rolled after OCR found pseudo-text rendered at legible size - render_from_art.mjs emits JPEG by default (558 KB PNG -> 84 KB mozjpeg q85); the ZH 1200x630 card did not exist before this batch - 288 frontmatter fields migrated; the 144 v1 PNGs are gone - PostList's thumb helper keys off the base slug (a ZH card is zh-<slug>.jpg while the thumb is <slug>-800.webp, which 404'd the whole ZH listing) - [...slug].astro's <picture> regex accepts .jpg - the repo now carries the art inputs (metaphors.json, captions/<slug>.json, refreshed prompts_catalog.json) so a frame is reproducible from git alone
