Play no longer switches to fullscreen direct rendering: PIE now keeps the editor UI alive and renders the primary camera into the Viewport panel (new SceneRenderer::SetGameView flag; kDisplayDirect stays a manual fullscreen preview for later release form). Editor camera stops being driven during PIE, and viewport click-pick is gated off while playing (clicks are game input now). The Play/Stop buttons move out of the menu bar into a dedicated main toolbar row below it (centered, UE Main Toolbar semantics): green Play when idle; Pause (yellow, highlighted while paused) + Stop (orange) while playing. Ctrl+P hotkey kept. Stats "Pause Simulation" merged into the toolbar Pause; viewport overlay shows PAUSED accordingly.
