Depends on #117.

Adds a ZED Mini and its support to the default V2 bimanual assembly.

Changes

• Attach the support through the pedestal camera reference and connect the official ZED model through its component wrapper.
• Add the support visual and two closed collision meshes for its metal support and plastic shell, with consistent part identifiers.
• Support multiple collision geometries per link and update the example URDF and camera preview configuration.
• Include the official ZED description in CI.

Validation

• The compound-collision check verifies the generated count, origins and box dimensions against its input fixture.

• 30 existing tests pass on ROS 2 Jazzy, including the component adapter and model entrypoints.

• Collision meshes passed closed-surface and self-intersection checks. Visual part IDs and references were checked against the accepted geometry.

Review the camera assembly after #117.
