overview: chrome windows (Popup/Overlay) stay fully interactive

The cce-cloud launcher opened during overview was focused but dead to
input: the overview keyboard gate only passed presses to Overlay-mode
windows and the launcher runs as Popup — every press was silently
eaten (and worked after a click only because that click EXITED
overview, lifting the gate). The click itself was the second bug: the
overview content-press handler grabbed any window into the move-op,
whose tap-release focuses and zooms out of overview.

Popup now counts as chrome alongside Overlay in all three places: the
keyboard gate, the click-block exemption, and the overview press
handler, where chrome presses fall through to normal handling — the
launcher takes clicks and keys like always, and overview stays up.
Clicking a world window still zooms to it; background clicks still
exit.
