Add animation controller system, material assets and skeleton visualization
- .animctrl state machine asset (params/transitions/blend trees, 1D+2D directional blending) with Unity Animator-style editor panel: state list, transitions, params, directional pad preview driving live CrossFade on the selected entity - Split animation evaluation out of SceneRenderer into AnimationSystem/AnimationEvaluator; skin palettes with rest-pose fallback and blend-weight epsilon filtering - MaterialAsset (.material) with reload-safe preview tile pool (DropMaterial clears dirty refs before instance destruction) - EditorGizmoPass skeleton wires + viewport joint overlay; camera projection rework (baked Vulkan Y-flip, ortho support) - Editor/game build split via HELLOVULKAN_EDITOR option
