Refactor camera system to use quaternion rotations

Browse Source 
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.
