Show saw kerf on optimization report and allow rectangular cut-outs with corner radius

Ulrich:

I am using MaxCut for a private campervan conversion project where I am optimizing lightweight plywood sheets.

I would like to request two improvements:

  1. Please add the saw kerf value used during optimization to the job layout document header. This would help double-check machine setup and ensure the correct kerf is being used on the shop floor.
  2. Please add support for rectangular cut-outs inside parts, with the ability to define a corner radius. This would be very useful for features like sink cut-outs in worktops, especially when exporting to DXF for CNC, milling, or water-jet cutting.

These additions would make MaxCut even more practical for CNC and digital fabrication workflows.
