- Add get_world_state AI command that dumps ECS entities with Transform,
Camera, Material, Light, and Mesh summaries.
- Add set_material AI command to update albedo/roughness/metallic/texture.
- Expose both commands as MCP HTTP tools and stdio tools.
- Add Light component and support up to 4 directional lights via a Vulkan
uniform buffer (descriptor set 0) with std140 layout.
- Move per-frame lighting/camera data into the uniform buffer; push constants
now carry only MVP + material properties (96 bytes).
- Add Texture class for PNG loading and Vulkan image/view/sampler creation.
- Add per-entity combined image sampler descriptor set (set 1) and use it
for albedo texture sampling in the fragment shader.
- Generate a checkerboard floor texture in Program.cs.
- Add McpStdioServer for headless stdio MCP (Claude Desktop compatible).
- Add claude_desktop_config.json and scripts/start_mcp_engine.sh.
- Update CORTEX_ENGINE_ARCHITECTURE.md with runtime notes, CLI arguments,
Vulkan pipeline details, and MCP client configuration.
- All configs (Debug/Release/ReleaseAOT) build successfully.
- 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.
