Scribe/etch lines were being treated as cut contours by
ContourCuttingStrategy, receiving lead-ins and kerf compensation.
Now they are separated before ShapeProfile construction and emitted
as plain moves with LayerType.Scribe preserved.

Scales down lead-ins that would place the pierce point too close to the
opposite wall of small holes. Uses quadratic solve to find the maximum
safe distance inside a clearance-reduced radius. Adds Scale() method to
all LeadIn types and applies clamping in both the strategy and the
interactive preview.

Both ActionSelect and ActionZoomWindow had identical 29-line
GetRectangle methods; consolidate into the common base class.

PushBoundingBox left exactly partSpacing between bounding boxes, but the
geometry push inflates offset lines by halfSpacing + chordTolerance per
side (totaling partSpacing + 2*chordTolerance). The 0.002 overlap caused
RayEdgeDistance to return MaxValue for negative t, making the nearest
obstacle invisible and allowing the part to push through it.
Subtract 2*ChordTolerance from the BB push distance so the gap is wide
enough for the offset geometry lines to remain non-overlapping.

Cut-off parts use absolute coordinates in their programs, causing
Program.BoundingBox() to span from the origin to the cut-off position.
This made cut-offs invisible to GetLargestBoxVertically/Horizontally
since the oversized box straddled the cursor instead of acting as a
boundary. Derive thin obstacle boxes directly from CutOff definitions
and apply PartSpacing offset so fills respect spacing from cut lines.

- Extract MakePoint/AxisBounds/CrossAxisBounds helpers in CutOff to
eliminate repeated axis-dependent branching
- Simplify BuildProgram loop from 4 code paths to 2
- Use static EmptyExclusions to avoid per-part list allocations
- Fix double event subscription in ActionCutOff constructor
- Dispose debounce timer in DisconnectEvents
- Remove redundant BuildPerimeterCache call in OnMouseDown
- Extract TotalCutLength test helper, remove duplicate test

Replace CutOff.BuildPerimeterCache (List<Shape>) with Plate.BuildPerimeterCache
(Dictionary<Part, Entity>) throughout. Consolidate two Regenerate overloads into
a single method with optional cache parameter. Fix Shape intersection bug where
non-intersecting entities added spurious Vector.Zero points to results.

Adds a new action that lets users place cut-off lines on plates by
clicking. The action auto-detects horizontal vs vertical axis based on
mouse proximity to plate edges, shows a dashed preview line that
follows the cursor, and adds the cut-off on left click. Pressing
Escape returns to selection mode.

Add SelectionChanged event to PlateView and display the selected part's
location and size in a new status bar label. Shows combined bounding box
when multiple parts are selected.

Move fill algorithms to OpenNest.Engine.Fill namespace:
FillLinear, FillExtents, PairFiller, ShrinkFiller, Compactor,
RemnantFiller, RemnantFinder, FillScore, Pattern, PatternTiler,
PartBoundary, RotationAnalysis, AngleCandidateBuilder, and
AccumulatingProgress.
Move strategy layer to OpenNest.Engine.Strategies namespace:
IFillStrategy, FillContext, FillStrategyRegistry, FillHelpers,
and all built-in strategy implementations.
Add using directives to all consuming files across Engine, UI,
MCP, and Tests projects.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add Vector-based overloads to SpatialQuery (ray casting, edge distance,
directional gap, perpendicular overlap) and PartGeometry (directional
line filtering) to support pushing parts along any angle, not just
cardinal directions.
Add Compactor.PushBoundingBox for fast coarse positioning using only
bounding box gaps. ActionClone shift+click now uses a two-phase strategy:
BB push first to skip past irregular geometry snags, then geometry push
to settle against actual contours.

Moves async fill+progress orchestration into PlateView so ActionClone's
Ctrl+F fill shows the NestProgressForm dialog.

"Length" is more natural than "height" for flat plate materials.
Renames the field on OpenNest.Geometry.Size, Box.Height property,
and all references across 38 files.

- Add bounding box rejection in HasOverlaps to skip expensive
Part.Intersects (CNC→geometry conversion) for non-adjacent parts.
Eliminates ~35% CPU in IsBetterValidFill for grid layouts.
- Optimize RayEdgeDistance: access Line fields directly instead of
property getters (avoids Vector struct copies), inline IsEqualTo
with direct range comparison (avoids Math.Abs), and precompute
deltas for reuse in interpolation.
- Cache line endpoints in DirectionalDistance outer loop to avoid
repeated struct copies in the inner loop.
- Add fill timer to ActionClone.Fill, displayed in PlateView status
bar as "Fill: N parts in M ms".

Add PushDirection.Right and PushDirection.Up to RotationSlideStrategy so
parts can approach from all four directions. This discovers concave
interlocking arrangements (e.g. L-shaped parts nesting into each other's
cavities) that the original Left/Down-only slides could never reach.
Introduce BestFitCache so best-fit results are computed once at step size
0.25 and shared between the viewer and nesting engine. The GPU evaluator
factory is configured once at startup instead of being wired per call
site, and NestEngine.CreateEvaluator is removed.

GPU factory logic belongs with the GPU implementation, not the UI.
Changed from internal to public and updated namespace to OpenNest.Gpu.

Pressing Escape from ActionSelect now restores the previous action
(e.g. ActionClone) instead of staying in Select mode. Adds
ConnectEvents() to the Action base class for action resume support.

ActionClone.Fill() now computes the largest open rectangle from the
cursor position (trying both vertical and horizontal) and passes it
to the engine, so fills no longer overlap existing parts.
Pattern fills try all convex hull edge angles to find the rotation
that maximizes part count.

SetPlate clears SelectedParts, which broke bounds drawing and rotation
for surviving actions. Add OnPlateChanged hook so ActionClone can
re-populate SelectedParts after a plate switch.

SetPlate unconditionally reset the action to ActionSelect, clearing
the clone pattern when switching plates. Add SurvivesPlateChange
virtual property to Action base class so actions can opt in to
persisting across plate changes.

Merge ActionAddPart into ActionClone by adding a Drawing constructor,
eliminating the redundant class. ActionClone now handles both adding
new parts from a drawing and cloning selected part groups. Added
Ctrl+F fill support for groups using FillLinear pattern tiling, and
adopted quadrant-aware push directions from ActionAddPart. Refactored
FillLinear to extract shared helpers and add a Fill(Pattern) overload
for tiling arbitrary part groups across the work area.
