PolygonHelper.ExtractPerimeterPolygon always used OffsetSide.Right
assuming CCW winding, but DXF imports can produce CW winding. This
caused the spacing polygon to shrink inward instead of expanding
outward, making parts overlap during nesting.
Now detects winding direction via polygon signed area and selects
the correct OffsetSide accordingly.
Also adds save_nest MCP tool and a BOM-to-nest builder utility
(tools/NestBuilder) for batch-creating nest files from Excel BOMs.

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.

G-code output was concatenated without spaces (e.g. N1005G0X1.4375Y-0.6562).
Now emits standard spacing (N1005 G0 X1.4375 Y-0.6562) across all motion
commands, line numbers, kerf comp, feedrates, M-codes, and comments.

Load IPostProcessor plugin DLLs from Posts/ directory (same convention
as the WinForms app) and run them after nesting via --post <name>.

The previous default of 0.125 was too large for typical use, causing
cut-off lines to be pushed unnecessarily far from parts.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Adds project dependency in .sln and project reference in OpenNest.csproj
so the Cincinnati post processor DLL builds before the main app, ensuring
it's always available in the Posts/ directory.

Each unique part geometry (drawing + rotation) is written once as a
reusable sub-program called via M98, reducing output size for nests
with repeated parts. G92 coordinate repositioning handles per-instance
plate placement with restore after each call. Cut-offs remain inline.
Controlled by UsePartSubprograms (default false) and PartSubprogramStart
config properties.

The WinForms app's LoadPosts() scans Posts/ for IPostProcessor DLLs.
A build target copies the Cincinnati DLL there so it appears in the
Nest > Post menu automatically.

- Move ProgramVariable and ProgramVariableManager from
OpenNest.Posts.Cincinnati to OpenNest.Core/CNC (namespace OpenNest.CNC)
so they can be used internally in nest programs
- Add parameterless constructor to CincinnatiPostProcessor that loads
config from a .json file next to the DLL (creates defaults on first run)
- Enums serialize as readable strings (e.g., "Inches", "ControllerSide")
- Config file: OpenNest.Posts.Cincinnati.json in the Posts/ directory

Select cut-offs by clicking their lines instead of a grip point.
Drag is axis-constrained with live regeneration during movement.
Selected cut-off highlighted with bright blue 3.5px line.

Polygon.OffsetEntity now computes proper miter-join offsets using edge
normals and winding direction, with self-intersection cleanup. CutOff
exclusion zones use geometric perimeter offset instead of scalar padding,
giving uniform clearance around parts regardless of cut angle.

- Use CultureInfo.InvariantCulture in CoordinateFormatter, SpeedClassifier,
and CincinnatiPreambleWriter to prevent locale-dependent G-code output
- Make CincinnatiPostConfig sealed per spec
- Fix SpeedClassifier.Classify threshold to >= (matching spec)

Orchestrates CincinnatiPreambleWriter and CincinnatiSheetWriter to produce
a complete Cincinnati CNC output file from a Nest; includes 4 integration tests.

- Regenerate cut-off programs after RotateSelectedParts so cut lines
update when parts are rotated, not just moved
- Change default CutDirection from TowardOrigin to AwayFromOrigin so
cuts start at the origin axis

- 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.

The NFP engine was a thin wrapper that delegated all single-drawing
operations to DefaultNestEngine. Remove the engine and its registry
entry to reduce dead code.

RemnantFiller: add placed parts as a single envelope obstacle instead
of individual bounding boxes to prevent the next drawing from filling
into inter-row gaps. Remove the topmost bounding-box part to create a
clean rectangular boundary.
PairsFillStrategy: guard against recursive invocation — remnant fills
within PairFiller create a new engine that runs the full pipeline,
which would invoke PairsFillStrategy again causing deep recursion.

Swap the ComboBox drawing selector with the same DrawingListBox control
used in EditNestForm, placed in a resizable SplitContainer. Add selection
highlighting and HideQuantity option to DrawingListBox. Show a centered
loading message while computing, and allow switching drawings mid-compute.

Test drawings used CCW winding, causing OffsetSide.Left to produce
inward offsets. The BestFit pipeline then positioned pairs so actual
shapes overlapped, failing all 1232 candidates. Changed to CW winding
to match CNC convention where OffsetSide.Left = outward.
Also fixed EdgeStartSequencer test: centerPart at (25,55) was only 4.5
from the top edge (plate Y=60), closer than midPart at (10,10). Moved
to (25,25) for correct ordering.

Add "Sheet Cut-Off" menu item to the Plate menu that activates
ActionCutOff placement mode on the active PlateView.

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 DrawCutOffs and DrawCutOffGrip methods to PlateView for rendering
cut-off lines and selection grip handles. Includes CutOffSettings and
SelectedCutOff properties, plus GetCutOffAtPoint for hit-testing.

Make quantity trimming direction-aware: DefaultNestEngine uses TrimAxis
(virtual property on NestEngineBase) so HorizontalRemnantEngine removes
topmost parts instead of rightmost. Rename ShrinkAxis.Height → Length
for consistency with Width/Length naming used throughout the codebase.

CutOff computes cut segments along a vertical or horizontal axis,
excluding zones around existing parts with configurable clearance.
CutOffSettings controls part clearance, overtravel, minimum segment
length, and cut direction (toward/away from origin).

Height shrink now uses HorizontalRemnantEngine (minimizes Y-extent)
and width shrink uses VerticalRemnantEngine (minimizes X-extent).
IterativeShrinkFiller accepts an optional widthFillFunc so each
shrink axis can use a different fill engine.

- Evaluate pair candidates in parallel batches instead of sequentially
- Add GridDedup to skip duplicate pattern/direction/workArea combos
across PairFiller and StripeFiller strategies
- Replace crude 30% remnant area estimate with L-shaped geometry
calculation using actual grid extents and max utilization
- Move FillStrategyRegistry.SetEnabled to outer evaluation loop
to avoid repeated enable/disable per remnant fill
