"""Read the in-app terminal pane in the Hermes desktop GUI.

The buffer lives in the desktop renderer (xterm.js), so this round-trips through
|
|
the gateway's blocking-prompt bridge (as `clarify` does): tui_gateway emits
|
|
``terminal.read.request``, the renderer answers ``terminal.read.respond``. Lives
|
|
in the ``desktop_ui`` toolset, enabled only for desktop-sourced sessions.
