refactor: update useLoop composable to replace raycaster with events

- Modified the `useLoop` composable to utilize `events` instead of `raycaster`, aligning with the recent changes in the Tres context structure.
- This change enhances the integration with the updated event system, ensuring better context handling during the rendering loop.
