feat: pure Vulkan P/Invoke renderer — no wrappers, SDL3 window, SPIR-V shaders
- Engine.Graphics: restored interfaces (IRenderContext, IRenderer, RenderBackendFactory), loaders (ObjLoader, GltfLoader), ProceduralMesh, MeshMath, SceneSerializer - Engine.Graphics.Vulkan: pure P/Invoke to libvulkan.so.1/vulkan-1.dll - VulkanNative: library loading, function pointer loading via vkGetInstanceProcAddr - Vk: static function cache for ~80 Vulkan functions, all delegate types - VulkanTypes: ~50 structs, ~20 enums matching Vulkan C headers - VulkanContext: instance, physical device, logical device, surface, memory types - VulkanSwapchain: swapchain, image views, depth image, render pass, framebuffers - VulkanPipeline: graphics pipeline, descriptor set layout, shader modules - VulkanBuffer: vertex/index/uniform buffers, staging, memory allocation - VulkanRenderer: command buffers, sync (semaphores/fences), render loop, 2 frames in flight - GLSL 450 shaders: PBR lighting (Fresnel, ACES, gamma), directional+point lights - Compiled to SPIR-V via @webgpu/glslang WASM - CortexEngine.App: switched to vulkan backend, removed Raylib/OpenTK/ImGui refs - Tests: all 66 pass (ObjLoader, MeshMath, ProceduralMesh, SceneSerializer, etc.) - Camera tour: 16 poses, screenshots captured, clean shutdown
