Add ChrFont, a reader for Gravograph .CHR engraving fonts, plus UI to
convert placed text into engraved geometry in the CAD converter.
The .CHR files are obfuscated with a single-byte XOR. Different
GravoStyle releases use different keys (0x2F in older versions, 0xCF in
the 7000 series, and others across the font library), so the key is
auto-detected from byte 1 of the file: the font name is ASCII stored as
UTF-16LE, so the high byte of its first character is 0x00 in plaintext
and the raw byte equals the key. This reads every font in a GravoStyle
install regardless of version, not just one hardcoded key.
UI: right-clicking a text item in EntityView raises TextConvertRequested;
CadConverterForm renders it via ChrFont with H/V alignment and adds the
result on an ENGRAVE layer.
Tests use Xunit.SkippableFact and a gitignored test-config.json so the
suite points at a local .CHR file without committing proprietary assets.

Extract MText and TextEntity from the CadDocument during DXF import
and render them in the EntityView. Handles text alignment (left/center/
right via InsertPoint vs AlignmentPoint) and replaces AutoCAD control
codes (%%p → ±, %%d → °, %%c → ⌀). MText formatting codes are
stripped before display.

Place circle labels on the circumference using golden angle distribution
so concentric circles don't overlap. Hide labels when the entity is too
small on screen to fit the badge.

Labels are drawn at each entity's midpoint with a filled background
circle for readability. Toggle via "Labels" checkbox in the detail bar.

Etch marks for up bends are now real geometry entities on an ETCH layer
instead of being drawn dynamically. They flow through the full pipeline:
entities → FilterPanel layers → ConvertGeometry (tagged as Scribe) →
post-processor sequencing before cut geometry.
Also includes ShapeProfile normalization (CW perimeter, CCW cutouts)
applied consistently across all import paths, and inward offset support
for cutout shapes in overlap/offset polygon calculations.

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

DxfImporter now filters ETCH entities (like BEND) since etch marks are
generated from bends during export, not cut geometry. GeometryOptimizer
no longer merges lines/arcs across different layers and preserves layer
and color on merged entities. EntityView draws etch marks directly from
the Bends list so they remain visible without relying on imported ETCH
entities.

Add toggleable pierce point drawing to PlateView that shows small red
filled circles at each rapid move endpoint (where cutting begins). Wire
through View menu, EditNestForm toggle, and MainForm handler.
Also rename RectangleShape/RoundedRectangleShape Width/Height to
Length/Width for consistency with CNC conventions, update MCP tools and
tests accordingly. Fix SplitDrawingForm designer layout ordering and
EntityView bend line selection styling.

Replace sidebar Panel+Splitter with SplitContainer for resizable file
list / filter panel. Sort file list alphabetically on insert. Widen bend
line dash spacing and draw ETCH layer entities on top of bend lines so
etch marks are visible.

ConvertProgram.ToGeometry() created entities without setting Color,
defaulting to Color.Empty (alpha=0). After ededc7b switched from
Pens.White to per-entity colors, these rendered fully transparent.
- Add explicit colors to all SpecialLayers (Cut=White, Rapid=Gray, etc.)
- Set entity Color from layer in ConvertProgram for lines, arcs, circles
- Add GetEntityPen fallback: treat Empty/alpha-0 as White
- Add bend line rendering and selection in EntityView/CadConverterForm
- Fix SolidWorksBendDetector MText formatting strip for bend notes

Add per-entity IsVisible flag and wire up the Colors and Line Types
checkedlistboxes to filter entities by exclusion — checking an item
hides matching entities from the preview and from drawing export.

Move all projects from Source/ to repository root for simpler navigation.
- Remove External/ dependency DLLs (will use NuGet packages)
- Remove Installer/ NSIS script
- Replace PartCollection/PlateCollection with ObservableList
- Add packages.config for NuGet dependencies
