Added quaternion and vector structures from the cglm library for handling 3D rotations and directions. Added a new function `euler_to_quat` to convert Euler angles to a quaternion representation. Changed the `camera_t` structure to replace separate forward, up, and right vectors with a single rotation quaternion. Changed the `camera_create` function to accept a rotation quaternion instead of separate direction vectors. Changed the `scene_init` function to initialize the camera with a default rotation quaternion. Changed the `ensure_camera_aspect_ratio` function to maintain the camera's rotation quaternion. Changed the `screen_render_pixel`, `scene_render_tile`, and `scene_render` functions to compute camera coordinates based on the quaternion rotation.
