PEP-exported programs carry arc centers that are not equidistant from the
start and end points (e.g. I0.03 on a 0.0598 chord). Building the arc from
the end radius left its start off the previous move's end, so contours
failed to chain. Project the center onto the chord's perpendicular bisector.
The Draw Offset display offset each entity separately, which left spikes and
inverted loops wherever a feature is narrower than the spacing (1.nest,
P260417-06). Inflate the flattened region with Clipper instead, which
collapses narrow features and drops holes that close up.

Repo-wide sweep with the pinned CSharpier 1.3.0 tool. Whitespace and
line-wrapping only; OpenNest.Engine.Tests (109) and OpenNest.IO.Tests
pass after reformat, full solution builds 0 errors.
Added .csharpierignore so csproj/config XML keeps its existing layout
(CSharpier's XML wrapping churns attributes with zero benefit).
Formatting is now enforceable: dotnet csharpier check . passes.
GeometrySimplifier/ArcFit now fit arcs that pass exactly through run
endpoints while balancing tangency error between trusted and estimated
directions, fixing arcs that previously bulged or broke tangent
continuity at fillet/compound-curve junctions.
GravographIS post processor gains per-layer (engrave/cut) tool passes
via a new GravographISPostConfig, so ENGRAVE/ETCH-tagged geometry runs
as a separate scribe pass with its own feed/depth and an operator
pause before the cut pass (spring-floated spindle needs a tool swap).

Inline sub-program geometry into the parent geometry list using Offset
as the starting curpos, replacing the Shape-wrapping approach.
