Switch from downloading pre-built Flutter SDK tarballs to cloning from git. Flutter only provides x64 Linux tarballs, but cloning from git allows Flutter to bootstrap itself with the correct Dart SDK for any host architecture (amd64 or arm64). Also reduces image size from ~4GB to ~1.7GB for Android variant. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
