feat(v2.3.1): velocidad de descarga en MB/s en tiempo real

Browse Source 
Calcula delta de bytes entre cada tick del loop (0.3 s) y lo convierte
a MB/s con un decimal via awk. Se muestra en la misma línea de progreso:

  →  [########------------]   42%  (1823 de 4340 MB)  23.5 MB/s

Sin Content-Length: "1247 MB  23.5 MB/s"
Al completar: muestra tamaño final sin velocidad (limpia la línea).
