feat: enhance configuration management and improve session variable handling

## Configuration Updates
- **Add .mcp.json and .env files** to .gitignore to prevent sensitive data exposure
- **Update MEMORY_FILE_PATH** in .mcp.json to reflect new file location
- **Modify code-audit command** in .mcp.json to include XAI_API_KEY in environment variables

## Session Variable Improvements
- **Refactor define_variable method** to use I32 type for session variables
- **Update tests** to reflect changes in variable type handling

## Documentation
- **Add comments** to clarify safety and usage in memory management functions

These changes improve security by managing sensitive configurations and enhance the session variable handling for better type consistency.
