🎉 Initialize project with gitignore and Prettier config

Sets up development environment standards for a multi-language project.
Gitignore covers common artifacts from macOS, editors, Python, Node.js,
and build tools. Prettier config ensures consistent formatting across
file types with sensible defaults and language-specific overrides.
