A queued echo now records its Inbox position like transcript and steering
echoes. Later splices move that position, so a canceled splice that removes
the row retires the echo even when no Inbox projection ever showed it, for
example when the Turn is stopped right after queueing. A claimed row still
waits for its admitted message, and the queue dock still hands the echo over
to the Host row it renders.
The fold-room e2e no longer samples the running status slide or the
`data-chat-tail-pinned` mark that this branch removed. It asserts that fold
room below a short answer takes the new Turn's growth without scrolling
through Turn end, that the room never grows back, and that the running
status only moves down.
