Priority-based snapping: when the cursor is within 10px of an entity
endpoint or midpoint, snaps to it instead of the nearest contour point.
Diamond marker (endpoint) or triangle marker (midpoint) replaces the
lime dot to indicate active snap. Also refactors OnPaint into focused
helper methods and adds Arc.MidPoint().

The push algorithm's copy distance formula (bboxDim - slideDistance)
produced distances smaller than the part width when inflated boundary
arc vertices interacted spuriously, causing ~0.05 unit overlaps between
all adjacent grid parts.
Two fixes applied:
- Clamp ComputeCopyDistance to bboxDim + PartSpacing minimum
- Use circumscribed polygons (R/cos(halfStep)) for PartBoundary arc
discretization so chord segments never cut inside the true arc,
eliminating the ChordTolerance offset workaround
Also parallelized three sequential fill loops using Parallel.ForEach:
- FindBestFill angle sweep (up to 38 angles x 2 directions)
- FillPattern angle sweep for group/pair fills
- FillRemainingStrip rotation loop
Added diagnostic logging to HasOverlaps, FindCopyDistance, and
FillRecursive for debugging fill issues.
Test result: 45 parts @ 79.6% -> 47 parts @ 83.1%, zero overlaps.

Add SegmentsForTolerance(double) to Arc and Circle that calculates the
minimum segments needed to keep sagitta within the given tolerance.
Add Shape.ToPolygonWithTolerance() that uses it per arc/circle.
Push distance now uses 0.08" chord tolerance instead of a fixed segment
count, giving appropriate resolution for each arc based on its radius.

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
