Godot 4.3 project for Quest 3 that replaces the browser-based WebXR
teleoperation with a native app using XR_FB_body_tracking (70 joints).
Key advantage: chest-relative wrist tracking eliminates head-position
subtraction artifacts and decouples body rotation from arm control.
Godot app: body_tracker.gd, teleop_client.gd, webcam_display.gd
Robot server: teleop_server.py (WebSocket, replaces Vuer ~900→~250 lines)
Drop-in wrapper: native_tv_wrapper.py (compatible with teleop_hand_and_arm.py)
