Add save and load commands that snapshot the entire Docker volume (SDK, extensions, runtimes, output artifacts, stamps) plus project config to a compressed tar.gz archive. This allows transferring build state between machines so that `avocado load` + `avocado provision` works without re-running install/build. - `avocado save -o state.tar.gz` exports volume + config - `avocado save -o state.tar.gz --include-src` also packs src_dir - `avocado load -i state.tar.gz` restores volume, config, and src
When --sdk-arch targets a different architecture than the host, Docker needs QEMU binfmt_misc to run the foreign-arch container. Docker Desktop has this built-in, but Linux Docker Engine does not. This detects the missing handler and auto-registers it via tonistiigi/binfmt, with a clear error message if registration fails.
