hideIdlePrompt method
void
hideIdlePrompt(
Hides or restores the persistent idle prompt. While hidden, the editor
draws no prompt between commands (used so the AI agent owns the screen);
an explicit prompt question still shows. The host repaints the prompt
when restoring.
Implementation
void hideIdlePrompt(bool hidden) {
if (_promptHidden == hidden) return;
_promptHidden = hidden;
if (interactive && !_passthrough && _promptCompleter == null) _refresh();
}
