### Changed

**All packages**
- `LVSParser` renamed to `WktParser` everywhere: C++ class, header (`wkt_parser.hpp`), source (`wkt_parser.cpp`), C# wrapper (`WktParser.hpp/.cpp`), Python binding (`bind_wktparser.cpp`, exposed as `geompp.WktParser`), all CMakeLists, vcxproj files, tests, and documentation. The old name is gone entirely — update any call sites.

### Added

**C++ core**
- `GeometryCollection2D` / `GeometryCollection3D`: heterogeneous container holding any mix of 2D (or 3D) primitives. Supports `Add()`, `Get(index)`, `Size()`, `ToWkt()`, `FromWkt()`, `ToFile()`, `FromFile()`, `AlmostEquals()`, and `operator==`.
- `Polygon2D::Make(points, holes)`: new overload that accepts an outer ring and a list of hole rings. Validates that the outer ring is CCW and each hole is CW; throws on violation.
- `Polygon3D::Make(points, holes)`: same, additionally validates that outer ring and all hole rings are coplanar.
- `are_ccw(points)` / `are_cw(points)` (2D, declared in `point2d.hpp`): free functions returning `true` when the ordered point list has the specified winding.
- `are_coplanar(points)` / `are_ccw(points)` / `are_cw(points)` (3D, declared in `plane.hpp`): 3D winding and coplanarity checks on point lists.
- `WktParser::FromWkt(wkt)`: static method — parse any WKT string into a `ReturnSet` (already existed as `Get()`, renamed to `FromWkt()` for consistency with the serialization API).
- `WktParser::ToWkt(shape)`: static method — serialize a `ReturnSet` back to its WKT string; throws on `nullopt`.

**C# / NuGet**
- `Polygon2D.Make(array<Point2D^>^ points, array<array<Point2D^>^>^ holes)` exposed.
- `Polygon3D.Make(array<Point3D^>^ points, array<array<Point3D^>^>^ holes)` exposed.

**Python / PyPI**
- `GeometryCollection2D` and `GeometryCollection3D` exposed with full `add()`, `get()`, `size()`, WKT, file I/O, and equality support.
- `Polygon2D.make(points)` and `Polygon2D.make(points, holes)` exposed.
- `Polygon3D.make(points)` and `Polygon3D.make(points, holes)` exposed.
- `are_ccw(points)` / `are_cw(points)` exposed for `list[Point2D]`.
- `are_coplanar(points)` / `are_ccw(points)` / `are_cw(points)` exposed for `list[Point3D]`.
- `WktParser.from_wkt(wkt)` — parse a WKT string; returns a geometry object or `None`.
- `WktParser.to_wkt(shape)` — serialize any geometry object to its WKT string; raises on `None` or unsupported type.

### Tests

**C++ (`geompp_tests`)**
- `test_polygon2d.cpp`: added `WktWithHoles`, `WithHoles_Valid`, `WithHoles_PerimeterCW_Throws`, `WithHoles_HoleCCW_Throws`, `WithHoles_HoleTooFewPoints_Throws`.
- `test_polygon3d.cpp`: added same suite plus `WithHoles_NonCoplanar_Throws`.
- `test_utils.cpp`: added `AreCCW_2D`, `AreCoplanar_3D`, `AreCCW_3D`.
- `test_wkt_parser.cpp` (renamed from `test_lsv_parser.cpp`): existing `FromFile` test retained.

**Python (`geompp_python/tests`)**
- `TestWktParser` (renamed from `TestLVSParser`): added `test_get_returns_geometry`, `test_get_returns_none_on_unknown`, `test_to_wkt_point2d`, `test_to_wkt_linesegment2d`, `test_to_wkt_point3d`, `test_to_wkt_none_raises`, `test_to_wkt_roundtrip`, `test_to_wkt_unsupported_type_raises`.
- `TestPolygon2D`: added holes construction, CCW-outer throw, CW-hole throw, and too-few-points throw cases.
- `TestPolygon3D`: added same suite plus non-coplanar throw.
- `TestFreeFunctions`: added `are_ccw`/`are_cw` (2D), `are_coplanar`/`are_ccw`/`are_cw` (3D).
