companion: above every overlay that opens, with a hop back in

Remapping only when the assistant opened left her under rofi and the
keybind reminder, which map on the same Overlay layer later. She now
remaps on Hyprland's openlayer event for any namespace but her own,
restarting the timer so a burst of openings ends with her on top.

The bare remap read as a flicker. Unmapped she now counts as away, so
her figure drops out unseen during the 400 ms and plays its entrance
when she is back: a vanish and a hop in.

-- She is on the Overlay layer and remaps when the assistant canvas opens:
