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.
Pulls the rapid-walk logic (sub-program unwrapping, first-pierce lookup,
incremental-vs-absolute handling, first-rapid skipping) out of
PlateRenderer.DrawRapids into a reusable RapidEnumerator in Core so it
can be unit-tested and reused outside the renderer.
