fix(sandbox): run GitPush from host to fix local-remote push + harden against sandbox escapefix/dockersandbox-gitpush-host-security
DockerSandbox.GitPush was running `git push` inside the container via
`docker exec`, but the origin remote URL is a host filesystem path that
was never bind-mounted into the container — only hostDir is. This caused
`exit status 128` in TestDockerSandbox_RealContainer_Lifecycle.
Fix: run `git -C hostDir push origin -- <ref>` from the host (mirroring
HostSandbox.GitPush), so local-path remotes are reachable. Two security
flags prevent a compromised workspace from escaping onto the host:
- `-c core.hooksPath=/dev/null` neutralises any hooks planted in .git/
- `-c protocol.ext.allow=never` blocks the ext:: pseudo-protocol
Also rejects refs starting with "-" and inserts "--" before the ref to
prevent argument injection.
