High-utilization pairs (>=75%) are no longer discarded for exceeding
the aspect ratio limit, since the material isn't being wasted.

Wires the OpenNest.Data layer into the UI: adds project reference, creates MachineConfigForm (tree-based editor for machines/materials/thicknesses with import/export), and adds Tools > Machine Configuration... menu item.

Embeds CL-980.json as a resource in OpenNest.Data and adds EnsureDefaults()
to LocalJsonProvider, which seeds the machines directory on first run when empty.

One JSON file per machine named by GUID, stored in a configurable directory.
Supports save, load, list (as summaries), and delete with IO-error retry.

- Parts tab: shows all BOM items, editable Material/Thickness for
matched rows, grayed-out rows for items without DXF files
- Groups tab: auto-computed from parts with editable Plate Width/Length
per material+thickness group
- Editing Material/Thickness on Parts tab immediately re-groups
- Per-group plate sizes preserved across re-groups

Fill must be at index 0 (front) so it's processed last by the
docking layout engine. Edge docks at higher indices process first.

AutoSize with Dock.Fill child causes circular sizing and collapses
the GroupBox. Use fixed Height=200 instead.

Replaced absolute-positioned controls with TableLayoutPanel in the input
section and Dock-based layout for bottom buttons. Fixes controls being
hidden at non-100% DPI scaling.

- Add Fill control last so edge-docked controls get space first
- Remove stale hardcoded Location on bottom panel
- Switch to Sizable border with MinimumSize so user can resize

- Fix critical: use MdiParentForm (custom property) instead of MdiParent
(WinForms property) in ImportBom_Click to avoid InvalidOperationException
- Add null guard in CreateNests_Click
- Set Drawing.Material from BOM group
- Move DxfImporter creation outside loop
- Improve summary label text with reason descriptions

Task 9: CreateNests_Click validates plate dimensions, then for each
MaterialGroup creates a Nest with name '{job} - {thickness} {material}',
sets PlateDefaults (size, thickness, material, quadrant=1, spacing),
imports each matched DXF via DxfImporter, converts entities to Program
with leading RapidMove offset handling (same pattern as CadConverterForm),
sets Quantity.Required from BOM qty, then opens an EditNestForm for each
nest that has drawings. Summary MessageBox reports count and import errors.

Add argument validation to EllipseConverter.Convert for tolerance and
semi-axis parameters. Narrow bare catch in Extensions.cs spline method
to log via Debug.WriteLine. Remove unused lineCount variable from
SolidWorksBendDetectorTests.

Add EllipseConverter static class with foundational methods for converting
ellipse parameters to circular arcs: EvaluatePoint, EvaluateTangent,
EvaluateNormal, and IntersectNormals. All 8 unit tests pass.

When a file is loaded, a background task analyzes the entities for
simplification candidates and highlights the Simplify button with a
count when candidates are found. Button resets after simplification
is applied.

OptionsForm now shows checkboxes for each fill strategy, persisted via
the new DisabledStrategies user setting. FillStrategyRegistry exposes
AllStrategies and DisabledNames for the UI. MainForm applies disabled
strategies on startup via OptionsForm.ApplyDisabledStrategies().

New EngineOverlapTests verifies all engine types produce overlap-free
results. New StrategyOverlapTests checks each fill strategy individually.
StripeFillerTests updated to verify returned parts are overlap-free
rather than just asserting non-empty results. Remove obsolete FitCircle
tests from GeometrySimplifierTests (method was removed).

FillExtents falls back to the unadjusted column when iterative pair
adjustment shifts parts enough to cause genuine overlap. StripeFiller
rejects grid results where bounding boxes overlap, which can occur when
angle convergence produces slightly off-axis rotations.

Part.Intersects now filters out intersection points that coincide with
vertices of both perimeters (shared corners/endpoints), which are touch
points rather than actual crossings. Plate.HasOverlappingParts adds a
bounding box pre-filter requiring overlap region to exceed Epsilon in
both dimensions before performing expensive shape intersection checks.

Convert SimplifierViewerForm to partial class with standard WinForms
designer pattern. UI controls are now defined in the .Designer.cs file
with InitializeComponent(), enabling visual designer support.

Three bugs prevented the simplifier from working on ellipse geometry:
1. Sweep angle check blocked initial fit — the 5-degree minimum sweep
was inside TryFit(), killing candidates before the extension loop
could accumulate enough segments. Moved to TryFitArcAt() after
extension.
2. Layer reference equality split runs — entities from separate DXF
ellipses had different Layer object instances for the same layer "0",
splitting them into independent runs. Changed to compare Layer.Name.
3. Symmetrize replaced arcs with mirrored copies whose endpoints didn't
match the target's original geometry, creating ~0.014 gaps. Now only
applies mirrored arcs when endpoints are within tolerance of the
target's boundary points.
Also: default tolerance 0.02 -> 0.004, Export DXF button in
CadConverterForm for debugging simplified geometry.

Geometry Simplifier:
- Replace least-squares circle fitting with mirror axis algorithm
that constrains center to perpendicular bisector of chord, guaranteeing
zero-gap endpoint connectivity by construction
- Golden section search optimizes center position along the axis
- Increase default tolerance from 0.005 to 0.5 for practical CNC use
- Support existing arcs in simplification runs (sample arc points to
find larger replacement arcs spanning lines + arcs together)
- Add tolerance zone visualization (offset original geometry ±tolerance)
- Show original geometry overlay with orange dashed lines in preview
- Add "Original" checkbox to CadConverter for comparing old vs new
- Store OriginalEntities on FileListItem to prevent tolerance creep
when re-running simplifier with different settings
Bend Detection:
- Propagate bend notes to collinear bend lines split by cutouts
using infinite-line perpendicular distance check
- Add bend note text rendering in EntityView at bend line midpoints
DXF Import:
- Fix trimmed ellipse closing chord: only close when sweep ≈ 2π,
preventing phantom lines through slot cutouts

Use chars.Length instead of hardcoded 36 for modulus/division since
the character set excludes 0 and O. Pad with '2' (first valid char)
instead of '0' to avoid ambiguity.

Without this, simplified geometry was lost on file switch and
not included in the final GetDrawings output.

Add "Simplify..." button to the detail bar and wire up SimplifierViewerForm
as a tool window with lazy creation, positioning, and entity replacement on apply.
