Usage: showcase recreate <slug> [slug...] [options]

Force-recreate service containers to pick up a new Docker image.
Unlike 'restart', this ensures the container uses the latest image.

Options:
  --build     Rebuild the image before recreating
  --no-wait   Don't wait for the container to become healthy

Examples:
  showcase recreate mastra           # recreate with current image
  showcase recreate aimock           # recreate aimock (uses test compose)
  showcase recreate mastra --build   # rebuild + recreate
  showcase recreate mastra aimock    # recreate multiple services
