The connect-first handoff (D85) has the build chat call manage_connections before
anything else, and the backend watcher mints each app's link on its first pass. That
moves the row to `initiated`, which the card drew as the spinner plus "Waiting for
your browser…" although nobody had clicked Connect and no browser had opened. Try
again had the same gap: the fresh link is minted, not opened.
The card now remembers which rows the user opened from it. A minted link the user has
not opened shows as not connected with the Connect button; clicking Connect opens it
and shows the waiting cue; Try again clears it until the new link is opened.
