AlphaPipeline HIP-4 Mispricing

Finds monotonicity violations among Hyperliquid HIP-4 'above $X' price-binary markets: within the same underlying/expiry/period, a higher strike's Yes price should never exceed a lower strike's - any reversal is a logical inconsistency (quantified as violation_bp and a textbook max_riskless_profit_per_usd, before fees/slippage). Reuses hip4-price-ladder's cache - no new upstream call. Required `underlying`. Not investment advice. Paid in USDC on Base.
