Bump GitHub Actions and refine help banner

Update CI steps to use actions/checkout@v6 and actions/setup-python@v6. Revise ASCII help banner generation: import LOGO_ALPHA from the theme, remove static resource path, add max_width parameter, compute banner width from terminal size (clamped between min_width and max_width), and skip rendering the banner when stdout is not a TTY. Simplifies banner selection logic and keeps colored banner output when available.
