feat(terminal): add Ctrl+Shift+C/V copy/paste shortcuts

xterm captures all keyboard input which prevents standard clipboard
operations. Add custom key handler to intercept Ctrl+Shift+C for
copy (selection) and Ctrl+Shift+V for paste, without interfering
with Ctrl+C (SIGINT) or browser devtools shortcut.
