Contract 6.22.0

The card tools, after the Elixir Gym's first run on them (feedback #102-#108).

• cards_archetype({cards}) answers an eight-card set, its main use, instead of timing out every time (#104). The exact-set lookup goes through the card index. A timeout hint names from/to only on tools that take them.
• Trophy bands are Trophy Road trophies. A ranked (Path of Legends) observation carries a rating, not trophies, and now sits in no band (#102). Before, the top-1,000 board filled under_5000. The season rollups were rebuilt, and a note says so wherever bands and ranked meet.
• A form said before a win condition keeps to that form: 'Evo Royal Hogs bridge spam' counts and filters only the Evo form's decks (#105). A bare name matches every form and says so.
• cards_card members.played counts the same population as season, so war duels are out (#103). It serves excluded, prior_win_rate and prior_basis, and insufficient_sample: true where the shrunk rate is withheld. It no longer claims a corpus prior where it shrinks toward the segment, and a player segment carries freshness (#107).
• cards_card history says when the mode mix moved under the series: ranked went from 18% to 92% of observations between July and September (#106). cards_synergy says anchor.decks counts observations, not deck identities (#108).

Additive fields (excluded, prior_win_rate, prior_basis, insufficient_sample) and corrected values (bands without ranked, members.played without duels, form-scoped archetype names).
