checked_u128_mul_i128: Multiply a u128 by an i128 returning i128 (checked). Computes u128 * i128 → i128. Used for A_side * delta_p in accrue_market_to.
compute_trade_pnl: Compute trade PnL: floor_div_signed_conservative(size_q * price_diff, POS_SCALE) Uses native i128 arithmetic (spec §1.5.1 shows trade slippage fits in i128).
