feat(ui): implement mobile navigation and rotating text

Add a responsive mobile navigation menu to the `Header` component, allowing users to easily access different sections of the portfolio on smaller screens. This includes a toggle button for opening/closing the menu and smooth animations for its appearance.

Introduce a `RotatingText` component in the `Hero` section to dynamically display different professional titles, enhancing the visual appeal and conveying diverse skills.

Update `package.json` to include `framer-motion` as a dependency, which is utilized for the new animations.
