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. Changed `sample_bsdf_simple_lit` and `sample_bsdf_pdf_simple_lit` to remove `const` from the `normal` parameter. Changed `scene_render` to take a pointer to `render_target_t` instead of returning it directly. Updated `main.c` to reflect new initialization functions for better memory management.
