Copy and paste do not work on Plasma 6.5 Beta

Describe the bug
CopyQ cannot access the clipboard on Plasma 6.5 Beta. This is due to missing support for the wayland protocol ext-data-control (see KDE bug). KWin dropped support for wlr-data-control in 6.5.

To Reproduce

Launch CopyQ on Plasma 6.5 Beta
Copy to and paste from clipboard history does not work.

Version, OS and Environment
CopyQ Clipboard Manager 12.0.0
Qt: 6.8.3
KNotifications: 6.18.0
Compiler: GCC
Arch: x86_64-little_endian-lp64
OS: KDE Flatpak runtime

KWin dropped support for wlr-data-control in 6.5.

🤦 Oh no! Is there another protocol I can use?

I was basically using the same code as KGuiAddons: https://invent.kde.org/frameworks/kguiaddons/-/tree/master/src/systemclipboard?ref_type=heads

I'm afraid that this may end up as for Gnome, where clipboard can be accessed only from Gnome extensions.

Thanks for reporting this!

Looks like the code was updated. I will sync it with CopyQ and perhaps try to link the KGuiAddons library instead of using the modified code.
