Build me a fast command line tool that shows useful information about a local Git repository right in the terminal.

When I run it inside a repo, I want it to print a clean, nice looking summary with things like the repo name, primary language breakdown, code stats, authors, and other helpful project details, all without needing internet access. It should feel polished and customizable, so I can choose what gets shown, hide extra lines I do not want, change the text styling, ignore certain files or folders, and export the output as JSON or YAML if needed.

Make it work on Linux, macOS, and Windows, and keep it snappy even on bigger repositories. If you need to check current docs or examples online while building it, go ahead. Please also make sure it has a simple command like running it in a repo folder or passing a path directly, and that the default output looks good in a normal terminal.
