Fantasy UI that still moves when the game freezes

The look of the current runner is finally one piece. We dropped in Fantasy Menus and Warrior HUD and spent the week making them belong to the same game.

The hard part was the pause menu. If you pause with timeScale = 0, every animator that lives in scaled time dies with the world. Buttons should still fly in. We moved those UI animators to unscaled time so the menu can breathe while the samurai is frozen mid-slide.

Next is a dedicated Game Over screen. High score deserves a stage, not a leftover pause panel.
