v24.3 crashed in cp_version() during the copy-package-manager-trees step because its sandbox needs bubblewrap (not present in the runner apt list), and cp --version returned empty output inside the broken sandbox. Installing bubblewrap and bumping to v25.3 which has tighter sandbox fallback behavior. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
