Git init

Summary

`git init` turns a folder into a Git repository, creating the hidden `.git` directory that tracks every change you make from that point on. The repository stores metadata, objects, references, and configuration inside `.git`, while the working tree remains the files you actually edit.

• 1Run `git init` in a fresh folder and inspect the resulting `.git` directory. Validate your understanding by applying it in a small practical example.
• 2Add a `.gitignore` file before your very first commit. Test the result on both a successful path and an invalid or unexpected input.
• 3Learn the difference between initializing locally vs cloning an existing remote repo.
