feat: add freecad-mcp to Crush integration

Browse Source 
Build and validate FreeCAD MCP Server (v1.25.0).

Changes:
- mcp-freecad-wrapper.sh: Created wrapper script with container cleanup
- crush.json: Added freecad-mcp entry with type: stdio and timeout: 180
- STATUS.md: Updated working MCP list and detailed status table
- JOURNAL.md: Documented integration with full validation results

Validation:
- Container builds successfully (317MB, Python + uv)
- MCP protocol handshake verified with initialize request
- Protocol version 2024-11-05 confirmed
- Server name: FreeCADMCP, version 1.25.0
- Wrapper script tested and working
- Environment variable: PYTHONUNBUFFERED=1
- External dependency: FreeCAD with MCP addon (warning if not running)

Similar to blender-mcp:
- Both Python-based with uv package manager
- Both require CAD application with addon running
- Both show warning on startup when CAD app not connected
- Both still initialize properly for MCP protocol handshake

This is second MCP added in alphabetical order after filtering
out already working MCPs (audiobook, bitwarden, blender, cloudron,
context7, docker, drawio, elasticsearch).

Following ADR-007: Sequential Server Validation - one MCP at a time,
awaiting user validation before proceeding to next MCP.
