Tvdb's default episode query answers at most 500 rows and states no total.
One Piece (1999), Crayon Shin-chan (1992) and Detective Conan (1996) each
answer exactly 500 while holding over a thousand, so the contradiction rule
added in the previous commit read every long-running show as contradicted:
the pack books more episodes than "the authority holds", and the rule that
exists to stop a wrong anime title would have stripped the right one from
every file of the season.
A capped list now records that it is capped (`tvdb:capped:<id>`, so a warm
cache answers the same question a cold one did) and contradicts nothing;
titles for the episodes the page does hold still ride.
Test: a 500-row page with a 501-episode pack keeps ` - Episode 1` and lists
no contradiction. Red before the change, proved in a copy of the tree with
the cap raised past the fixture.
