Function render_to_buffer_with_target 

pub fn render_to_buffer_with_target(
    object_dir: &Path,
    camera_transform: &Transform,
    object_rotation: &ObjectRotation,
    config: &RenderConfig,
    target_point: Vec3,
    targeting_policy: TargetingPolicy,
) -> Result<RenderOutput, RenderError>

Render a YCB object and attach the target metadata used for the camera pose.

This is useful when callers generate camera transforms with generate_targeted_viewpoints and need the live render output to carry the exact per-render pivot point for downstream pose compensation.
