A feed is read up to 200 MB, not 50 (#357)

The Herd with Colin Cowherd's feed is 62 MB, its whole back catalogue, and had failed every check
since the 50 MB cap of #295 came in on 2026-10-19. The cap was there for an MP3 given as a feed;
200 MB still stops that, at four times the largest real feed seen.
