fix(parse): pack titles and degenerate ranges

COMPLETE before the season tag was weak junk, so it stayed in
the title and exact-title matching failed silently (#135). It
now closes the boundary wherever it lands.

S01-S01 produced no claim because the dash-range branch required
last > season; a degenerate range is one season's pack, matching
the rule match_episode lifted.
