fix(tui): restore cursor on Ctrl+C interrupt during spinner

    Fixes bounty issue #1522

    The cursor remained hidden if the user interrupted the application with
    Ctrl+C while a spinner was active. This was because the terminal
    state wasn't fully restored in the Ctrl+C handler path.

    This change explicitly calls terminal.show_cursor() when handling the
    Ctrl+C interrupt signal in the event loop, ensuring the terminal
    is left in a usable state.
