feat(creatures): animate creature walk cycles

Browse Source 
Add a Gait component synchronized over the network and procedural animation for model nodes. Load animation parameters from assets/model/creature/pig/animation.json and apply leg swing, body bob, and head motion based on gait. Refactor Gait into its own header for reuse.
