feat: paru auto-install + ASCII Header + Continue-Prompt

- paru wird jetzt in detect_environment() auf frischen Systemen installiert
  (vorher nur in preflight, das bei --fresh nie durchlief)
- install_aur_helper() von preflight nach utils.sh verschoben (global verfügbar)
- Header von Cherokee-Zeichen ('Ꮎ Ꮇ Ꭼ Ꮢ Ꮎ Ꮑ') auf ASCII ('O M E R O N')
  umgestellt — Cherokee zeigte auf manchen Terminals Fragezeichen
- Continue with installation? Prompt nach Banner als erster interaktiver Schritt
- basic mode header jetzt sauberes ASCII (===== statt Box-Zeichen)
