feat: setup project structure and tooling

- Initialized npm project and added core dependencies (React, Express, etc.).
- Added development dependencies (TypeScript, Vite, ESLint, Prettier, etc.).
- Configured TypeScript (`tsconfig.json`).
- Configured Vite (`vite.config.ts`) with React plugin and API proxy.
- Configured ESLint (`.eslintrc.cjs`) and Prettier (`.prettierrc.cjs`, `.prettierignore`).
- Added standard `.gitignore`.
- Created basic project structure (`src/client`, `src/server`, `public`).
- Created default `.env` file (PORT=3001, PUBLIC_URL=http://localhost:3001).
