Chat+ link previews: a link in a chat shows its page's title, text and picture, YouTube playable in place

Browse source 
X's web chat shows a link as a bare card. An X tab on a chat page may now ask native code
(link_preview, x-capture only, chat pages only) for one link's preview. Native code fetches it:
https and public hosts only (addresses checked and pinned), never X's hosts, no cookies or
referrer, redirects re-checked, page head <= 512 KB, images <= 1.5 MB by magic bytes as data:,
30 fetches a minute, memory-only cache. Only the link leaves the page. On by default (owner,
2026-10-10).
