feat: add RoverStrip component with interactive rover simulation

- Implemented RoverStrip component for a canvas-based rover simulation.
- Created roverEngine module to handle terrain generation, rover physics, and particle effects.
- Added useHeroActive hook to manage visibility and tab state for the rover animation.
- Updated main.tsx to ensure the page scrolls to the top on reload.
