- Updated cleanup.sh to avoid recreating .env during cleanup, preventing exposure of default passwords before firstboot. - Modified firstboot.sh to create .env from .env.example only if it doesn't exist, ensuring no sensitive data is present before initialization. - Added support for Docker Hub and GitHub tarball download acceleration via new environment variables WEKNORA_GH_PROXY and DOCKER_REGISTRY_MIRROR. - Implemented a mechanism to prune old WeKnora images based on the current version, reducing image size and maintaining a clean environment. - Enhanced README.md with instructions for using the new acceleration features and image pruning options.
