feat: Initialize BuzzMaster project structure

Sets up the foundational project structure for the BuzzMaster Live Quiz Platform. This includes:

- **Project Initialization:** Creates `package.json` with necessary dependencies (React, React Router DOM, Vite, TypeScript).
- **Vite Configuration:** Configures Vite for development and building, including server settings and environment variable handling.
- **HTML Entry Point:** Sets up `index.html` with basic structure, Tailwind CSS, Google Fonts, and ESM import maps.
- **React Entry Point:** Configures `index.tsx` to render the main `App` component.
- **TypeScript Configuration:** Defines `tsconfig.json` for the project.
- **Git Ignore:** Adds standard files and directories to `.gitignore`.
- **README and Metadata:** Includes a basic `README.md` and `metadata.json` describing the project.
- **Type Definitions:** Establishes core type definitions in `types.ts` for game state, user roles, players, teams, and questions.
- **App Component:** Creates a basic `App.tsx` component with routing and initial game state management, including logic for local storage fallback and API sync.
- **Component Stubs:** Adds placeholder components for `PlayerView`, `AdminDashboard`, and `SpectatorView`.
