Update character model with refined bone structure and visual details

Refactors the `character.f3d` model by restructuring bone hierarchy, separating torso into upper and lower parts, and adjusting limb and head attachment points. Visual elements like eyes, nose, mouth, shirt, and pants are also updated with new primitive shapes and colors.
