Dropped all code, documentation, and models related to macOS and WeChat 3.x (darwinv3) support, including command-line tools, model definitions, and documentation files. Updated README to clarify that only Windows and WeChat 4.x are supported, and improved instructions for image key acquisition. Enhanced restart-and-get-key logic with status callbacks and retry handling for more robust key extraction after WeChat restarts.
