fix(focus): update focus policy handling for Wayland and clipboard interactions

- Improved focus policy logic for fullscreen windows in Wayland and Treeland modes, ensuring proper focus behavior for screenshot and recording functionalities.
- Enhanced clipboard handling by checking for the presence of the clipboard daemon, allowing for better confirmation of data transfer to the clipboard.
- Updated comments for clarity regarding focus policy changes and clipboard signal handling.
