fix: pin Antigravity user data to home PVC to survive pod restarts

Without explicit --user-data-dir and --extensions-dir, Antigravity may
default to a path outside /home and lose settings on restart, causing
the setup wizard to reappear. Pinning both to $HOME ensures they land
on the persistent home PVC.
