The Identity card gains an "Operating system" row: the pretty name as text,
the raw identity chain as its tooltip, and a leading OsIcon resolved by the
same most-specific-first walk as the clients. lucide deliberately ships no
brand marks, so os-icon.tsx vendors the ten as inline currentColor SVGs
(the brand-mark precedent, the plugin-registry pattern), falling back to a
generic monitor for a chain nothing recognizes. Row grows optional icon/title
props rather than a fork; stories cover Bazzite, Windows and the
unknown-distro degradation; labels land in both message files.
