Server instructions

ComboCheck checks Polymarket Combo (parlay) quotes. To check a quote: call search_markets for each leg to get its position_id, then check_combo_quote with those ids and the quoted price in cents. Fair price is the legs' probabilities multiplied together (assumes independent legs). Always show the user the ComboCheck link in the result.
