HookeFeeHookA protocol-fee hook for a single hXMAX/USDG pool that charges a 2%–4% USDG-only fee per swap based on the pool price's deviation from an oracle price. Fees on the specified stablecoin leg are pre-taken in beforeSwap via BeforeSwapDelta; fees on the unspecified leg are taken in afterSwap via AfterSwapReturnsDelta. Also records tick-cumulative observations to serve a TWAP via consultMeanTick.
