Add a "Configure git remote" step that points origin at the Gitea host (git@git.lastcloud.io) and pins the host to port 22222 in ~/.ssh/config so git doesn't default to port 22 and get rejected by the agent offering too many keys. Idempotent: reuses existing config on re-run. Also adds git to the prerequisite checks and renumbers the steps to 1-7.
