// Run starts the full-screen TUI and blocks until the user quits (Ctrl+C /

// cmd/pigo's dispatch calls it on the (no prompt + TTY + no --no-tui) path and
// maps its error to the process exit code. The alt-screen is entered/left via
// the View returned by the root Model, so a clean return here restores the
// terminal to the user's prior scrollback.
