Add two new commands for efficient file access from blob archives: cat command: - Print file contents to stdout using HTTP range requests - Support multiple files (concatenated in order) - Validate files exist and reject directories before output - Normalize leading slashes for consistent path handling - Respect --quiet flag after validation cp command: - Copy files/directories from archive to local filesystem - Parse ref:/path format (e.g., ghcr.io/repo:v1:/config.json) - Detect source type (file vs directory) from archive using Stat() - Support multiple sources from different refs (grouped to avoid re-pulling) - Flags: --recursive/-r (default: true), --preserve, --force/-f - Consistent overwrite behavior: skip existing by default, use -f to overwrite - Check destination exists before reading file content (avoid unnecessary downloads) Both commands use lazy archive loading - only manifest + index are downloaded upfront, with actual file data fetched via HTTP range requests on demand.
