Change Window Icon (OSC 1)

<VTSequence unimplemented sequence={["OSC", "1", ";", "Pt", "ST"]} />

Change the window icon name to t. The exact method of locating the icon data through the icon name is platform-dependent.

Ghostty and most modern terminal emulators do not implement this sequence as its behavior is not well-defined or even possible on all platforms, which is also the conclusion reached by Foot.
