Covers StaleImageError / check_stale / check_stale_path, the BottleBackend.launch template method (skip_stale flag), stale_checks functions across docker / smolmachines / macos-container backends, _build_images cached paths in the macOS backend, image_created_at edge cases in both docker and container util modules, the CLI stale loop (headless die, interactive decline, interactive confirm + retry), and ConfigStore.cached_image_stale_warning_days fallback paths. Diff-coverage: 488/507 changed lines covered (96.3%).
