Floating a dock rips it from the row and reshuffles the rest, so
PopoutWindow opens an ADDITIONAL frameless top-level window instead:
12px outer resize halo (border painted OUTER_GRIP inside the real edge
so an outside-looking grab still works), hand-painted borderless
titlebar glyphs, close hides and keeps geometry. DockTitleBar puts the
popout button next to the close box. The console log adopts it: dock
floating disabled, the pop-out view is a second QPlainTextEdit fed by
the same emitter (a shared QTextDocument would make two views fight
over one layout), clear() clears both.
