git — Your Local Safety Net

git remembers every version of your work: every save is a point you can return to. This skill installs it (if the Layer 1 installer didn't) and gives it an identity — the name and email it stamps on every saved version.

This is local only. No GitHub account, no SSH keys, no remote — those wait for the github skill at Launch, because pushing to a remote only earns its keep when you ship. Safe to re-run any time: already-configured steps report green and move on. This skill never uninstalls or overwrites a working git.
