Design for training an XGBoost model to predict which rotation
angles are worth trying during FillLinear, reducing the 36-angle
sweep to 4-8 predicted angles in narrow-work-area cases.

Address spec review issues: add third call site (Fill groupParts),
reuse ComputeCandidateRotations, fix step ordering for ToNestParts
before scoring, cap N to 500 and item.Quantity, clarify BoundingBox
is a property.

Spec for adding NFP-based placement as a competing strategy
in NestEngine.FindBestFill() for non-rectangular parts.

Clarify engine return type ownership, cancellation propagation into
parallel loops, quantity decrement sequencing, conditional phase
behavior, plate navigation lockout, and MDI child close handling.

- Drop Circle.ToArcFrom (zero-sweep problem), keep Circle in shape
and handle in ConvertShapeToMoves with full-circle ArcMove
- Use point-distance tolerance for Arc.SplitAt instead of angle
comparison to avoid wrap-around issues at 0/2pi
- Simplify SplitAt return types to non-nullable tuple
- Add ArgumentException guard in ReindexAt
- Add throw for unexpected entity types in ConvertShapeToMoves
- Document absolute coordinate convention and shared references
- Clarify variable names for both replacement sites
The strategy output (lead-ins, start points, contour ordering) must be
saved in the nest file, so Apply() runs when parts are placed — not
during post-processing.

- 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).
