The 2s dim-poll fallback relied on _refreshSize() emitting a 'resize'
event to trigger recovery, which doesn't always propagate under tmux+ssh
— leaving Ink's frame buffer pinned to the old layout until the user
resized again. Extract the recovery body and call it directly whenever
OS-reported dims differ from the last recovered size.
