feat: switch default backend to Silk.NET OpenGL
...
- OpenGLRenderContext: Initialize() + CreateOpenGL() for non-blocking
- OpenGLWindow: Initialize() instead of Run(), CreateGL() method
- Program.cs: default backend is now 'opengl', SwapBuffers per frame
- ImGui guarded: only initialized for RaylibRenderer, ObjectManipulator
checks _imGuiAvailable before calling ImGui.GetIO()
- 66/66 tests, 145 FPS with OpenGL backend

revert: remove shadow mapping attempts, restore clean renderer
...
Shadow mapping via Raylib doesn't work reliably:
- Rlgl.GetMatrixModelview returns zeros with custom FBO
- MaterialMapIndex binding doesn't map to expected texture units
- DrawModelEx resets texture state internally
Restored to last working state without shadows.
Consider direct OpenGL backend for shadow mapping.

fix: shadow map re-bind after DrawModelEx + transpose lightViewProj
...
- Bind shadow map on MaterialMapIndex.Emission (unit 1) per entity
- Re-bind via Rlgl.ActiveTextureSlot(1)+EnableTexture after DrawModelEx
(DrawModelEx resets texture state internally)
- Transpose lightViewProj matrix (Raylib row-major → OpenGL column-major)
- 66/66 tests, 145 FPS

fix: remove shadow mapping, keep all other improvements
...
Shadow mapping removed — Raylib's DrawModelEx doesn't support
multi-texture-unit binding needed for shadow map sampling.
Kept: linear gamma, per-channel Fresnel, point/directional lights,
correct CW normals, backface culling, floor entity.
66/66 tests passing.

fix: rlgl depth FBO shadows, correct normals, linear gamma, per-channel Fresnel
...
- Shadow mapping via rlgl: custom depth FBO (2048x2048, 24-bit depth texture)
instead of color-attachment approach. Proper depth-only render pass.
- Shadow map bound via MaterialMapIndex.Emission (texture unit 1), sampled
in shadow receiver shader with PCF 3x3 soft shadows.
- Fixed inverted normals: Cross(ac, ab) for CW winding in OBJ files.
- Linear workflow: pow(albedo, 2.2) before lighting, pow(result, 1/2.2) after.
- Per-channel Fresnel: vec3 F0 + (1-F0)*pow(1-HdotV,5) instead of F0.x.
- Single CollectLights call after BeginMode3D.
- Shadow pass after BeginDrawing (inside frame).
- Backface culling disabled globally for mixed-winding meshes.
- Point light support: Light.Point/Directional factory methods, attenuation,
ImGui inspector with type combo, position/range for point lights.
- Floor rendered for both light types (shadow receiver or main shader).
- 66/66 tests passing.

fix: restore rendering after shadow mapping attempt
...
Shadow mapping via DrawModelEx doesn't work — Raylib's material system
only supports texture unit 0, shadow map sampling needs unit 1.
Additional uniforms in fragment shader also broke NVIDIA GLSL uniform
layout, causing render artifacts. Reverted shader to pre-shadow state.
Shadow pass infrastructure (RenderShadowPass, shadow shader, RT) kept
but disabled. 66/66 tests passing.

feat: Dear ImGui editor, GLTF materials, scene serialization
...
- ImGuiLayer: entity inspector (Transform/Material/Light/Camera editing),
hierarchy panel, debug overlay with FPS graph (rlImgui-cs + ImGui.NET)
- GltfLoader.LoadWithMaterials: extracts PBR albedo, roughness, metallic,
base color texture from glTF files
- SceneSerializer: save/load ECS world to/from JSON with custom
Vector3/Quaternion converters, 6 tests
- ImGui disabled in tour/test mode to keep screenshots clean
- 66/66 tests passing
