feat: Introduce GUI Automation Tools for YAZE

- Added new GUI automation tools: gui-discover, gui-click, gui-place-tile, and gui-screenshot, enabling users to interact with the YAZE GUI programmatically.
- Implemented command handlers for each tool, allowing for automated GUI interactions such as clicking buttons, placing tiles, and capturing screenshots.
- Updated documentation to include usage instructions and examples for the new GUI tools, enhancing user experience and accessibility.
- Ensured compatibility with the test harness by requiring YAZE to run with the `--enable-test-harness` flag for GUI automation functionalities.
