Agent Skills: jj-vcs

Jujutsu (jj) is a powerful Git-compatible version control system with innovative features like automatic rebasing, working-copy-as-a-commit, operation log with undo, and first-class conflict tracking. This skill is triggered when the user says things like "use jj", "run jj commands", "jujutsu version control", "migrate from git to jj", "jj rebase", "jj squash", "jj log", or "help with jj workflow".
