changes.txt #6: sync homepage "Latest news" from the News hub

Add tools/build_listings.py: copies the top 3 cards from each language's News
hub into the homepage "Latest news" block (marker-wrapped), so editing the News
page now updates the homepage. The News hub stays the hand-edited source of truth
(it may hold curated teaser cards without a detail page).

Also: fix the Gallery meta description (was a copy of the FAQ text) and add a
durable gallery override to seo_inject.py; refresh llms.txt / links-for-bots.
