Master added head-raise markers, common-line shared cuts and remainders to
the CI Fiber's own contour extractor, which this branch replaced with Core's
shared PostContours. Those now live in the shared model: PostContour carries
Raised, IsCommonLine and RemainderWinding, and Classify gives remainders the
perimeter macro on their perimeter's side and shared cuts no kerf side.
ContourWinding uses PortableMath for trig, as master's Core guard requires.

Move the CI Fiber post's contour extraction and winding into Core as
OpenNest.CNC.Posting.PostContours and ContourWinding, so every post can
take sheet- or part-frame contours with the perimeter and kerf side
already chosen instead of re-deriving them. CI Fiber now writes from
the shared model; its golden output is unchanged.
Scribe marks are never picked as the perimeter and get no kerf. A cut
that resumes after suppressed moves starts a new contour where they
end, so it is no longer cut as a chord across the gap.
Add tests for a square with a hole in sheet coordinates, identical
contours from absolute and incremental part/hole programs, rotation,
and the kerf side for both windings.
