feat: scaffold initial Cheatsheet Hub application

This commit establishes the foundational structure for the Cheatsheet Hub project.

It includes the setup of a Vue 3, Vite, and TailwindCSS stack, along with core application features:

- **Routing:** Configures `vue-router` for Home, Cheatsheet List, and Cheatsheet Detail pages.
- **State Management:** Implements a `pinia` store for theme management (dark/light mode) and mock data.
- **UI Components:** Adds reusable components like `NavBar`, `CheatsheetCard`, and `PrintButton`.
- **Styling:** Integrates TailwindCSS with custom base styles, dark mode support, and print-friendly optimizations.
- **Dependencies:** Adds key libraries including `marked` for content rendering.
