feat(git-gate): provision ~/.gitconfig pushInsteadOf in the bottle

provision_git now does two things: copy the host cwd's .git (when --cwd is set, existing behavior) and write ~/.gitconfig with pushInsteadOf rules for each bottle.git entry. A 'git push <real upstream URL>' from inside the agent transparently rewrites to 'git://<gate>/<name>.git' so the gate gets first crack at the incoming refs. pushInsteadOf (not insteadOf) keeps fetch on the original URL — v1 of the git-gate is push-only scope per PRD 0008. The render helper is exposed for testing without docker.
