Pull Request Overview

This PR introduces a cross-platform GitHub Actions workflow and refactors several modules for MSVC compatibility and improved portability.

• Add CMake-based CI matrix for Linux and Windows.
• Implement cross-platform time handling and use std::move in key places.
• Replace templated Triangle with concrete classes and update numeric types to double.

• This change bypasses the object's transform when computing the world-space intersection point. Consider restoring transform * transformed_ray.at(t) (or equivalent) to correctly account for any object transformation.

    rec.p = ray.at(t); // Ponto de volta para o espaço global

libs/Prism/src/scene.cpp:4

• The implementation uses std::put_time, which requires <iomanip>. Please add #include <iomanip> to avoid compilation errors on some toolchains.

#include <sstream>

libs/Prism/include/Prism/ObjReader.hpp:27

• The constructor no longer initializes any members in an initializer list; ensure that all class members (e.g., cmap) are properly initialized or given default values to avoid uninitialized-member bugs.
