Copy text (Ctrl + C) should use Terminal protocol to copy to clipboard

[hongquan]

If user uses Harlequin on a remote machine, accessing via SSH, the "Ctrl +C" key won't copy the content to the local machine, because Harlequin attempts to use the clipboard of the remote machine.

Solution: Tell Terminal to talk with the clipboard. If using the same machine, Terminal will copy to the current machine clipboard. If using SSH, Terminal will copy to the local machine, not the remote one. The concrete solution is to use escape code (OSC 52). This will work without worrying about the existence of wl-copy, xclip.

This solution works on most of Terminal out there (Kitty, WezTerm, Alacrity, Ghostty etc.), except VTE-based ones like gnome-terminal.

Is it still not possible to use copy paste over ssh?

@redstonerti Yes, still. When pressing Ctrl + C, Harlequin says: "Error copying data to system clipboard".
