- Updated CloneVendorRepos.sh to use official ONLYOFFICE/docspace-mcp
  repository instead of ahujasid/docspace-mcp (which was outdated)
- Successfully built and validated docspace-mcp Docker container (236MB)
- Created wrapper script mcp-docspace-wrapper.sh with environment
  variables for DOCSPACE_HOST and DOCSPACE_TOKEN
- Added docspace MCP configuration to crush.json
- Updated STATUS.md with working status for docspace-mcp

MCP handshake test confirmed server responds correctly:
