The toolbar showed a static ~/public_html. The jailed shell now reports its cwd
via OSC 7 each prompt (jail rcfile keeps the user's prompt + emits it); xterm
captures it and the toolbar shows the full path (/home/<user>/...), updating as
the user cd's. Launcher/rcfile committed in deployment/ for reproducibility.
