- Rename Angle properties to ApproachAngle (avoid shadowing Math.Angle)
- Arc rotation from contour winding, not hardcoded CW
- Add winding parameter to LeadIn/LeadOut Generate methods
- Add exit point derivation from Plate quadrant
- Add contour re-indexing section (split/reorder at closest point)
- Add ContourType.cs and AssignmentParameters.cs to file structure
- Clarify normal direction convention
- Note SequenceMethod value 6 intentionally skipped (PEP numbering)

Lead-in, lead-out, and tab class hierarchy for CNC cutting
approach/exit geometry, using ShapeProfile + ClosestPointTo
for contour sequencing.

Replace three separate XML metadata files (info, drawing-info,
plate-info) and per-plate G-code placement files with a single
nest.json inside the ZIP archive. Programs remain as G-code text
under a programs/ folder.
This eliminates ~400 lines of hand-written XML read/write code
and fragile ID-based dictionary linking. Now uses System.Text.Json
with DTO records for clean serialization. Also adds Priority and
Constraints fields to drawing serialization (previously omitted).
