Jconn/delta_webots ? reverse-engineered prompt

Build me a simple Webots simulation of a delta grasper with a ROS2 wrapper so I can run and control it from ROS2.

I want the model to open and close like the demo, with a basic world, robot prototype, and any launch files needed to start everything easily. Please make it feel like a clean sample project that shows the grasper moving in Webots and exposes the main controls through ROS2 so I can send commands and see the motion. If you need to check current Webots or ROS2 docs online, go ahead.

Keep it lightweight and easy to run, with clear setup steps, and make sure the demo world works out of the box. If there are any joints, controllers, or messages needed for the grasper to move correctly, wire them up in a straightforward way.
