Splits that cross an interior cutout previously merged physically
disconnected strips into one drawing and drew cut lines through the hole.
The region boundary now spans full feature-edge extents (trimmed against
cutout polygons) and line entities are Liang-Barsky clipped, so multi-split
edges work. Arcs are properly clipped at region boundaries via iterative
split-at-intersection so circles that straddle a split contribute to both
sides. AssemblePieces groups a region's entities into connected closed
loops and nests holes by bbox-pre-check + vertex-in-polygon containment,
so one region can emit multiple drawings when a cutout fully spans it.

Add AutoTabMinSize and AutoTabMaxSize properties to enable automatic tab
assignment based on part size. Update CuttingParametersSerializer for
round-trip serialization and add tests.

DrawingSplitter now clips bend lines to each piece's region using
Liang-Barsky line clipping and offsets them to the new origin. Bend
properties (direction, angle, radius, note text) are preserved through
the entire split pipeline instead of being lost during re-import.
CadConverterForm applies the same origin offset to bends before passing
them to the splitter, and creates FileListItems directly from split
results to avoid re-detection overwriting the bend metadata.

Renamed OpenNest.Engine.Tests → OpenNest.Tests (directory, .csproj,
namespaces in all .cs files). Added OpenNest.IO project reference.
