"""
Setup Claude Desktop & Cursor MCP Configuration for Bartholomew v2.4
======================================================================
Writes claude_desktop_config.json so Claude Desktop and Cursor instantly
load Bartholomew as:
  1. An active MCP Guard tool server (`bartholomew-guard`).
  2. A resilient transparent security proxy (`bartholomew-proxy`) with
     in-flight secret redaction and transactional workspace rollbacks.
