Adds `--max-concurrent-downloads` flag to `container image pull` for configurable concurrent layer downloads. Fixes #715 Depends on apple/containerization#311 **Usage**: ```bash container image pull nginx:latest --max-concurrent-downloads 6 ``` **Changes**: - Add CLI flag (default: 3) - Thread parameter through XPC stack - Update to use forked containerization with configurable concurrency **Performance**: ~1.2-1.3x faster pulls for multi-layer images with higher concurrency **Tests**: Included standalone tests verify concurrency behavior and parameter flow --------- Co-authored-by: Claude <noreply@anthropic.com>
