Fix FastMCP stdio method for Claude Code integration

- Replace deprecated app.run_stdio() with app.run(transport="stdio")
- Update both src/mcpmc/mcpmc.py and src/backend/src/mcpmc.py
- Resolves AttributeError: 'FastMCP' object has no attribute 'run_stdio'
- Compatible with FastMCP 2.12.2+ API changes
- MCPMC Expert System now ready for uvx mcpmc execution
