New test files: - VulkanStructSizeTests.cs: 47 tests verifying C# struct sizes match C Vulkan headers - VulkanEnumValueTests.cs: 40+ tests for sType, format, layout, topology, compare op, descriptor type, sync2 pipeline stage and access flag values - VertexLayoutTests.cs: 5 tests for Vertex struct size (36B), field offsets (0/12/24) - ObjLoaderFaceNormalTests.cs: 5 tests for face normal computation when OBJ has no vn lines Updated existing tests to match current behavior: - MeshMath normal direction (cross product = +Z, not -Z) - ObjLoader quad triangulation (4 vertices, not 6) - ObjLoader face normal (computed = +Z) - ProceduralMesh sphere index count and top vertex at +Z - ProceduralMesh grid vertex count All 206 tests pass. Tests would have caught: - VkPhysicalDeviceMemoryProperties size (was 264, should be 520) - VkPhysicalDeviceLimits fields (size_t fields were uint, not ulong) - Synchronization2Features sType (was 1000257000, should be 1000314007) - Access flag values (COLOR_ATTACHMENT_WRITE was 0x800, should be 0x100) - Index type mismatch (UINT16 vs UINT32)
