Subject: [PATCH] feat: logging a install.log
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Dual output en print_*: colores ANSI a stdout + texto plano a $LOG_FILE (default install.log, overridable)
- El log es auxiliar: append guardado (su fallo de escritura — p.ej. log root-owned + doctor sin root — no aborta la operacion)
- Verificado: doctor sin root escribe al log; 0 codigos ANSI en el log
