Describe the bug
Copying text in query editor or query results on wayland compositors with no Xwayland shows an error message: "Could not access system clipboard.". With Xwayland, everything works fine without changing anything.

To Reproduce

1. Install and start a session of a wayland compositor which doesn't have Xwayland support e.g. niri
2. Open a terminal window e.g. kitty
3. Run harlequin duck.db
4. Type some text in the query editor
5. Select it with mouse or shift + arrow-keys
6. Hit control + c
7. Said error appears in the bottom right corner

Expected behavior
Text is copied with no error notification

Actual behavior
An error shows up and text is not copied.

Contributing
Are you interested in contributing a fix?

• Yes (I think this is due to a dependency on xsel/xclip which only works on X11. I can contribute a fix which will use wl-clipboard instead when XDG_SESSION_TYPE is equal to 'wayland' Upon reading the code, it seems like the TUI library component textual-textarea might need updating to fix this issue)
• Maybe
• No
