Translucent overlay shown over the main window while the Lua debugger is paused.
Renders a darkening vignette plus a centered card with a pause glyph, bold title and subtext — similar visual vocabulary to the startup SplashOverlay so the "wait" state feels native, with a somewhat more opaque treatment so the pause state reads clearly.
The overlay is a plain child QWidget of the main window, intentionally not a top-level Qt::Window: a child widget has no platform-window identity of its own (no NSWindow on macOS, no X11 window on Linux), so it can never surface as an independent entry in Mission Control / Alt-Tab, never carry its own drop shadow or zoom animation, and trivially stays glued to the main window for free — exactly like SplashOverlay does on the welcome page.
The paint is static (no animation): like the splash screen, the card is drawn once and stays put. While the debugger is paused the dialog also installs a QEvent::UpdateRequest filter on the main window (see PauseInputFilter in lua_debugger_dialog.cpp) to prevent re-entrant paints of the main window's backing store.
The overlay tracks its parent's size itself: the constructor installs an event filter on the parent and sets the initial geometry to the parent's rect. On QEvent::Resize the overlay resizes to the new parent rect and calls repaint() synchronously — required because an update() would post a QEvent::UpdateRequest to the top-level main window, which PauseInputFilter swallows. QEvent::Resize itself is not filtered, so the WM's resize is delivered to the main window and we see it here as well.
