Pull request overview

Fixes multiple example demo issues related to camera image / video recording, keyboard teleoperation behavior, and JoyLo dependency compatibility with Isaac Sim.

Changes:

• Add pip constraints when installing JoyLo to avoid incompatible numpy / opencv-contrib-python versions.
• Fix CameraMover recording paths by converting torch tensors to CPU numpy arrays, and make spline-derived values explicitly numeric.
• Adjust keyboard teleop release handling and correct printed key mapping for differential-drive control.

Using a fixed constraints file path in /tmp can collide when multiple installs run concurrently (and leaves a stale file behind). Prefer creating the constraints file with mktemp and removing it afterwards (e.g., via a trap) so the install is race-free and self-cleaning.

Can you directly add numpy<2 and opencv-contrib-python<=4.11.0.86 to the joylo setup.py file? I think this should work so we don't have to modify the main setup.sh file.

Also what's the reason for constraining opencv-contrib-python<=4.11.0.86?
