TASK 7 UI polish batch: scene/source row cleanup, dedup naming, full social handles — scenes are now pure selection rows (edit/trash/visibility icons and inline rename removed with EditSceneCommand/RemoveSceneCommand/ToggleSceneVisibilityCommand + Scene.IsEditing); source rows gained the trio (new EditElementCommand → inline rename via SceneElement.IsEditing, ToggleElementVisibilityCommand → eye flips IsVisible, open/slashed style rebound, hidden rows dim to 45%); duplicate resource names get a no-space incrementing suffix via shared NextSourceName (Image, Image2, Image3…) derived from actual names so deletions never collide (AddSource + AddReusedImage); social bar renders the full validated handle (MaxWidth=200 + TextTrimming removed from SocialBarRenderer and the preview template); side panels stay fixed 220/300; focus-loss capture lag documented in ai.md as a known OS limit (deferred) — the two real-App tests now share RealAppHost, a dedicated STA thread owning the single WPF App, instead of each calling new App(); new SourceNamingTests integration test (Text/Text2/Text3, delete-middle re-add no-collision) — 170 tests passing, 0 warnings
