fix: enable imageCubeArray feature + transition all 24 shadow layers
Two validation errors fixed:
1. imageCubeArray feature not enabled → added VkPhysicalDeviceImageCubeArrayFeatures
to device creation chain (pNext: cubeArray → sync2 → dynamicRendering)
2. Shadow layers 18-23 in UNDEFINED layout → transition ALL 24 layers
(MaxShadowLights * 6) instead of only numShadowLights * 6
Descriptor references all 24 layers via CubeArray view

feat: ImGui debug overlay — FPS, camera position, entity count
- ImGui.NET 1.91.6.1 integrated into Engine.Graphics.Vulkan
- VulkanImGui.cs: font atlas upload (staging → VkImage), sampler,
descriptor set (COMBINED_IMAGE_SAMPLER), separate pipeline with
alpha blending, no depth write, dynamic scissor
- ImGui shaders: imgui.vert (ortho MVP push constant) + imgui.frag
(font texture sampler)
- Dynamic vertex/index buffers (HOST_VISIBLE, grow on demand)
- IRenderer interface: BeginImGuiFrame/EndImGuiFrame default methods
- Program.cs: debug window with FPS, camera pos/target, entity count
- 0 critical validation errors, ~750 FPS with physics + ImGui

feat: depth buffer + 3D model matrix — rotating cube now looks correct
- Depth image (D32_SFLOAT) + image view created in VulkanSwapchain
- VkPipelineDepthStencilStateCreateInfo: depth test + write enabled, CompareOp=Less
- Push constant changed from float angle (4B) to mat4 model (64B)
- 3D rotation: RotateY * RotateX in renderer, applied via push constant
- Vertex shader: gl_Position = vp * model * vec4(pos, 1.0)
- Depth attachment in VkRenderingInfo + depth clear (1.0)
- Depth image layout transition (Undefined → DepthStencilAttachmentOptimal)
- New Vulkan functions: vkCreateImage, vkDestroyImage, vkGetImageMemoryRequirements, vkBindImageMemory
- New structs: VkPipelineDepthStencilStateCreateInfo, VkStencilOpState, VkImageCreateInfo
- New enums: VkCompareOp, VkImageType, VkImageTiling
- 0 validation errors

feat: push constants + UBO descriptor sets — rotating triangle with VP matrix
- Push constants: rotation angle (float) sent to vertex shader via vkCmdPushConstants
- UBO + descriptor sets: VP matrix (mat4) in uniform buffer, bound via VkDescriptorSet
- New Vulkan functions: vkCreateDescriptorSetLayout, vkCreateDescriptorPool,
vkAllocateDescriptorSets, vkUpdateDescriptorSets, vkCmdBindDescriptorSets,
vkCmdPushConstants
- New structs: VkPushConstantRange, VkDescriptorSetLayoutBinding,
VkDescriptorSetLayoutCreateInfo, VkDescriptorPoolCreateInfo,
VkDescriptorPoolSize, VkDescriptorSetAllocateInfo, VkWriteDescriptorSet,
VkDescriptorBufferInfo
- Per-frame UBO buffers (HOST_VISIBLE|HOST_COHERENT, 64 bytes each)
- Perspective projection + look-at camera (static, no ECS yet)
- Cleaned up debug logging in VulkanContext
- Zero validation errors

feat: rebuild Vulkan renderer from scratch — pure P/Invoke triangle (Vulkan 1.3)
- Complete rewrite of Engine.Graphics.Vulkan with pure P/Invoke (no wrapper libs)
- Vulkan 1.3: dynamic rendering (vkCmdBeginRendering/vkCmdEndRendering),
synchronization2 (vkQueueSubmit2, vkCmdPipelineBarrier2)
- Split types into VulkanHandles.cs, VulkanEnums.cs, VulkanStructs.cs
- Staging buffer → device-local vertex buffer pattern
- Correct swapchain semaphore indexing (per-image, not per-frame-in-flight)
- VK_EXT_debug_utils debug messenger with validation layer fallback
- Dynamic viewport/scissor (no pipeline recreation on resize)
- Simplified Program.cs to triangle-only rendering
- Removed old Silk.NET renderer, ImGui, PBR shaders, screenshot code
- Updated VULKAN_IMPLEMENTATION_PLAN.md with full architecture decisions
