Major MCP extension: adds tools for media content retrieval, OCR, real-time message subscription with webhook push, chat activity analysis, user profile, and shared file search. Implements persistent subscription management, new prompt templates, and real-time resource endpoints. Updates UI to display active MCP subscriptions, enhances CSV export with MessageID, and documents all new features in the changelog. Removes Dockerfile and docker-compose.yml.
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.
