Add initial project structure with backend and frontend setup

- Created backend structure with Go, including main application logic and API endpoints.
- Added Docker support for both development and production environments.
- Introduced frontend using Nuxt 3 with Tailwind CSS for styling.
- Included configuration files for Docker and environment variables.
- Established basic documentation for contributing, development, and deployment processes.
- Set up .gitignore and .dockerignore files to manage ignored files in the repository.
