Introduces a third person camera system with orbit camera, input handling (mouse/keyboard/touch/gamepad), display actor cloning, and camera-relative movement. Includes shared character utilities (animator, cloner, customizer) and an IExtraAnimHandler interface for optional animation extensions. Also includes generic base game fixes and extension system improvements.
