Resolved an issue where the `--address` and `--port` command-line arguments were being ignored due to a hardcoded IP address and an incorrect parsing loop.
This commit ensures that:
- The application correctly uses the address and port provided by the user.
- The application exits gracefully if required arguments are missing.
- The argument parsing logic is simplified and more explicit.
- Remove all X11-related code and dependencies.
- Create a mock Hyperion server for testing.
- Refactor the main application to be Wayland-only.
- Update the build system and documentation.
Added qDebug() statements to trace the execution flow and print out important values in the main function.
This will help to identify if the application is exiting prematurely.
