External lead-ins now sit on the line between the last internal cutout
and the next part's first pierce point, minimizing rapid travel. Cutout
sequencing starts from the bounding box corner opposite the origin and
iterates 3 times to converge the perimeter lead-in and internal sequence.
LeadInAssigner and PlateProcessor both use a two-pass approach: first
pass collects pierce points, second pass refines with next-part knowledge.

The approach rapid from sheet origin was drawing to part.Location (the
program coordinate origin) then a second rapid to the actual first
pierce point. This created a dog-leg through the part origin instead
of a single straight rapid to the lead-in. Also fixed PlateProcessor
using the original program's start point instead of the processed one
when the cutting strategy is applied on-the-fly.
