check_bet

Grade a sports bet against NegativeEV's game simulations. Input the bet as plain text (teams/players, market, line, odds); a multi-leg parlay in one string is graded leg by leg and priced as a whole. Use it when the caller has a SPECIFIC bet to evaluate — it prices a bet you name, it does not search for good bets, so there is nothing to send for 'what should I bet tonight'. Call `get_slate` first if it isn't known that today's games are simulated. Every result leads with `status`: `graded` (every leg scored — this is the only status that spends a check), `partial` (some legs scored), `ungraded` (the bet was understood but no leg is covered by the sims), `no_bet_found` (no bet recognized in the text), or `no_slate`, `unsupported_market`, `unsupported_sport`. When a leg doesn't score, `ungraded_legs[].reason` says why and `retry.rephrasing_helps` says whether re-wording could change the answer — it is false whenever the bet parsed, so do NOT resend the same bet in different words to work around an `ungraded` result. Covers MLB, WNBA, PGA, and ATP; any other sport returns unsupported_sport. Games that already started still grade, against the simulations from before first pitch (a pre-game projection, flagged as such).
