Removed several old BSDF-related functions in `Material.c` that are no longer needed due to the new structure.
Updated the `material_create` function in `Material.c` to accept the new render loop function pointer.
Updated the `path_trace` function in `PathTracing.c` to utilize the new `path_output` structure for managing light contributions and state transitions during path tracing.
Updated the `evaluate_bsdf_directional` function in `LightEvaluation.c` to return `path_output` and adjusted its internal logic to populate the output structure.
Updated the `evaluate_bsdf_const_sky` function in `SkyLight.c` to return `path_output` and modified its logic to handle light contributions correctly.
Updated the intensity of the sky light to `0.0f` during scene setup in `main.c`, effectively disabling it.

Changed several function signatures across multiple files to remove the `const` qualifier from parameters of type `vec3s` for improved flexibility.
Changed `material_collection_create` to `material_collection_init` for better initialization handling.
Changed `scene_create` to `scene_init` to return a boolean indicating success or failure.
Changed `render_target_create` to `render_target_init` for consistent initialization practices.
Changed `window_create` to remove `const` from its parameters for consistency.
Changed `evaluate_bsdf_directional` and `evaluate_bsdf_const_sky` to remove `const` from their parameters.
