Jujutsu (jj) Version Control Guide

Jujutsu is a modern, Git-compatible version control system. This project uses jj colocated with git.

Key Differences from Git

Concept	Git	Jujutsu
Staging area	Explicit `git add`	None - working copy IS a commit
Branches	Named refs	Bookmarks (auto-follow rewrites)
Stash	Separate stash stack	Not needed - just use commits
Amend	`git commit --amend`	Just edit files, or use `jj squash`
Identity	Commit ID only	Change ID (stable) + Commit ID
