Subject: [PATCH] feat(tests): add CLI and GPU command tests

Add tests for CLI argument parsing and GPU command generation to increase coverage and ensure future changes don't break functionality.

New Features
- Add unit test `verify_cli` to ensure Clap command is built correctly.
- Add unit tests for `xorg_intel`, `xorg_amd`, and `generate_xrandr_script` functions.
- Validate that generated Xrandr scripts contain expected provider settings.

Enhancements
- none

Bug Fixes
- none
