Subject: [PATCH] feat(terminal): add Cmd+C/V and Ctrl+Shift+C/V clipboard
 shortcuts

Intercept keyboard shortcuts in xterm.js so users can copy selected
text with Cmd+C (Mac) or Ctrl+Shift+C (Linux/Win), and paste from
system clipboard with Cmd+V / Ctrl+Shift+V. Without text selected,
Cmd+C still sends SIGINT as expected.
