The live screen now opens wide beside the chat while the bot works on it,
a file the bot presents as its result opens next to the conversation, and a
question that scrolled away gets a "Needs you" pill back to it. Focus is
derived from signals clients already have (pointer events, takeover
requests, a new `present` flag on attach_file, pending asks) by shared core
rules, so web and mobile agree and the behaviour stays deterministic.
The pane only moves on focus edges, never replaces a pane the user opened,
and learns per bot whether the screen should open on its own. Pane widths
persist per device. Mobile shows a pill that opens the computer route.
