*TRANSLATE THE CURVE TO REMOVE ZERO X-VALUES AT THE START OF THE CURVE*
=======================================================================

Translates a curve along the x-axis so that the first non-zero x-value becomes the new origin (x = 0), effectively removing any leading zero x-values at the start. Use this worker to align curves to their true starting point before further processing or comparison.

     - Input XY curve (vector) whose x-axis will be shifted so that the first non-zero x-value is translated to zero; leave unconnected if the curve will be supplied at runtime.
