- Route best-result updates to progress form preview in
PlateView.FillWithProgress (Ctrl+F path) — was still using
the old SetStationaryParts approach
- Only update results stats (parts, density, area) when
IsOverallBest so they match the preview display

Replace verbose value tuple with named PartPair record struct, extract
AnchorToWorkArea/PairBbox helpers to eliminate duplication, and delegate
RepeatColumns to FillLinear.Fill which already handles geometry-aware
column tiling with overlap fallback.

Polygon-polygon collision detection using convex decomposition (ear-clipping
triangulation) followed by Sutherland-Hodgman clipping on each triangle pair.
Handles overlapping, non-overlapping, edge-touching, containment, and concave
polygons. Includes hole subtraction support for future use.

FillGrid had no overlap check after perpendicular tiling of the row
pattern (Step 2), unlike Step 1 which had one. When geometry-aware
FindPatternCopyDistance underestimated row spacing, overlapping parts
were returned unchecked.
Changes:
- Make FillLinear.HasOverlappingParts shape-aware (bbox pre-filter +
Part.Intersects) instead of bbox-only, preventing false positives on
interlocking pairs while catching real overlaps
- Add missing overlap safety check after Step 2 perpendicular tiling
with bbox fallback
- Add diagnostic Debug.WriteLine logging when overlap fallback triggers,
including engine label, step, direction, work area, spacing, pattern
details, and overlapping part locations/rotations for reproduction
- Add FillLinear.Label property set at all callsites for log traceability
- Refactor LinearFillStrategy and ExtentsFillStrategy to use shared
FillHelpers.BestOverAngles helper for angle-sweep logic

Convex corners were being miter-joined (lines extended to a point)
because IntersectsUnbounded always finds an intersection for non-parallel
lines. Now checks the cross product of original line directions to detect
convex corners and inserts an arc instead.

- Part.Intersects: filter intersection points at a vertex of either
shape (was both), so edge-touching parts are not flagged as overlapping
- NestEngineBase.HasOverlaps: use epsilon-based bounding box pre-filter
consistent with FillExtents and Plate.HasOverlappingParts
- PartGeometry.GetOffsetPartLines: remove extra chordTolerance added to
spacing offset — was causing 0.002" gap beyond the intended part spacing

UpdateEtchEntities was removing all entities on the ETCH layer, which
also deleted user-added etch marks like part numbers. Now tags generated
bend etch lines with a BendEtch tag and filters on that instead.

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.

Shape.OffsetOutward produces inward offsets for certain rotated polygons,
causing geometry-aware copy distances to be too small and placing
overlapping parts. Root cause is in the offset winding direction
detection — this commit adds safety nets while that is investigated.
- FillLinear.FillGrid: detect bbox overlaps after geometry-aware tiling,
fall back to bbox-based spacing when overlaps found
- FillExtents.RepeatColumns: detect overlaps after Compactor computes
copy distance, fall back to columnWidth + spacing
- PairFiller/StripeFiller remnant fills: use FillLinear directly instead
of spawning full engine pipeline (avoids strategies with the bug)
- Add PairOverlapDiagnosticTests reproducing the issue
- MCP config: use shadow-copy wrapper for dev hot-reload
