fix: terminal title uses jink writeRaw instead of raw PrintStream

Terminal title now writes OSC 0 through Ink.Instance.writeRaw()
which goes directly to the JLine terminal. This eliminates garbled
characters caused by writing through intercepted System.out/err or
to streams that bypass the terminal's ANSI processing.
