Changed the pixel rendering function to include anti-aliasing using Sobol sampling in Renderer.c. Changed the path tracing function to adjust light shading context and Russian roulette logic in PathTracing.c. Changed the normal calculation logic to use a ternary operator in RayIntersection.c. Changed the Sobol sample calculation for consistency in Debug.c. Removed some items from the project roadmap in README.md. Modified the sample count from 64 to 16 in main.c, affecting rendering quality and performance.
