Subject: [PATCH] Fix intermittent Clipboard.SetText failure in Plot.cs

Added a retry loop for `Clipboard.SetText` inside the `SetClipboardText` method.
It attempts to set the clipboard up to 10 times with a 50ms interval to handle cases
where another application may briefly hold a lock on the clipboard. If it still fails,
it throws the error and shows the original message box.
