- triangle/quad/sphere tests: Update to use new Initialize signature with OpenGLDevice*
- triangle/quad/sphere tests: Use GetGLContext() for RenderDoc SetDevice
- triangle/quad/sphere tests: Add wglMakeCurrent in render loop
- triangle/quad/sphere tests: Update capture timing to frame 25-35
- unit test fixture: Add GetDevice() method
- unit test swap_chain: Update to use new Initialize signature
- Rename D3D12Enum.h to D3D12Enums.h for naming consistency
- Fix OpenGL unit test GLAD initialization by using gladLoadGL()
instead of gladLoadGLLoader(wglGetProcAddress) for fallback support
- Migrate remaining tests to use gtest_discover_tests for granular
test discovery (math, core, containers, memory, threading, debug,
components, scene, resources, input, opengl)
- Remove obsolete TEST_RESOURCES_DIR and copy_directory commands
from OpenGL unit test CMakeLists (minimal/Res doesn't exist)
- Update TEST_SPEC.md with performance metrics and per-module
build/test commands for faster development workflow
- Update CMake path references to use lowercase paths
