Added hotkey cycles for the new creatures

I added quick creature cycles to the number keys. Key 4 switches between Aurelia and Luma, key 5 between Sylph and Pip, and key 6 between Opal and Aster. The other creature shortcuts remain available alongside these pairs.

The cycles respect saved bindings and reject held-key repeats, so one press means one change. That makes comparing bodies quicker without forcing players to replace their existing control settings.

“Keys4,5 and6 cycle the new fox, butterfly and dragonfly alongside the existing variants.”

The clips use the actual number-key actions and show all six bodies in the current Character Studio. Each body is deliberately paused for a complete silhouette inspection; these switches are not flight or walking demonstrations.
