- Add ScreenshotCapture class to Engine.Graphics using Vulkan image readback.
- Integrate screenshot capture into MeshRenderer; request triggers readback on next frame.
- Add SixLabors.ImageSharp 3.1.11 for PNG encoding (patched for CVE-2025-54575).
- Add capture_screenshot AI command and MCP tool.
- Wire screenshot request into Program.cs with demo command.
- Expose swapchain surface format and image accessor for readback.
- Add Screenshots/ to .gitignore.
- Update CORTEX_ENGINE_ARCHITECTURE.md with MCP, Silk.NET.Vulkan, ImageSharp, and screenshot capture.
- Add Camera ECS component with view/projection matrices.
- Add Vulkan depth buffer to Swapchain: image, memory, view, render pass, framebuffers.
- Update VulkanPipeline with depth stencil testing and push-constant layout.
- Update vertex shader to use push-constant MVP matrix.
- MeshRenderer finds Camera, computes MVP per entity and pushes it.
- Program.cs creates a camera entity and keeps the cube rotating.
Build and run verified: window opens and FPS is reported.
- Add Vertex struct and Mesh ECS component (vertices + indices).
- Add Vulkan IndexBuffer for indexed draws.
- Add MeshRenderer that draws Mesh + Transform entities with vkCmdDrawIndexed.
- Add minimal .obj loader (positions, faces) and glTF/glTF-binary loader via SharpGLTF.Core.
- Rewrite shaders to 3D position + color; recompile to SPIR-V.
- Update VulkanPipeline for new vertex format.
- Ship a sample Content/cube.obj and wire Program.cs to load it.
- Remove TriangleRenderer (replaced by MeshRenderer).
