Detailed Description

Production IScreenProvider — a thin wrapper over QGuiApplication.

Enumerates QGuiApplication::screens() and relays screenAdded, screenRemoved, and per-screen QScreen::geometryChanged as the IScreenProvider lifecycle signals. The connector → PhysicalScreen conversion fills in the EDID-aware identifier via ScreenIdentity.

Always live: it wires up Qt's screen signals in its constructor, so it needs no explicit start/stop — matching QGuiApplication's own always-on screen tracking. Construct one and inject it via ScreenManagerConfig.
