Add crosshair to third-person mode and offset the player model to the side.

In third-person mode, the crosshair should remain visible in the center of the screen, while the player character is positioned slightly to the left or right of the camera. This would keep the area the player is aiming at visible instead of having the character’s head block the center of the screen. This would make third-person gameplay much more practical for placing blocks, breaking blocks, interacting with objects, and aiming at specific locations.
