as the thinking row: duration 1. The REATTACH variant

to a server-side turn, the placeholder says what is actually
happening — Reattaching… + the working-state spinner —
instead of a bare Thinking shimmer. */}

Thinking… from the instant anything is submitted (send,
answer, reattach — status flips synchronously, so it shows
before the first token, however slow the provider's
connection) until the first event lands, then it hands off
to the live stream — minimal change: the collapsible
reasoning row carries the SAME look, now with content.
Never collapsible itself (there is nothing to show yet).
