A task now opens at its newest step instead of where the previous task
was scrolled to, and a timeline read at its foot follows new steps
whatever the task's state (before, only while a step was running).
Read further up, it stays put; a round button over the message box
leads back down, with the count of the AI's new steps on its corner.
It replaces the "new steps below" pill (ui_ai_newest.js).
The side column's grip lay over the timeline's scrollbar, so grabbing
the scrollbar often resized the column instead. It now has a gap of its
own beside the scrollbar, drawn as three dots.
