fix: correct MCP server configuration to use shell scripts

Updated the configuration to use run_gemini.sh (macOS/Linux) or
run_gemini.bat (Windows) instead of directly calling Python.

The shell scripts properly:
- Set up the virtual environment
- Handle Python path resolution
- Run gemini_server.py (not server.py)

This ensures the server runs with the correct dependencies.
