DynamicFeeHook

ArbitrumRegistered

Charges a 25 BPS hook fee on each swap via afterSwapReturnDelta, with a 1.5x multiplier when inter-block price moves exceed 1%. Fees are forwarded to an owner-configured FeeDistributor. Uses per-pool, block-gated price tracking to prevent cross-pool oracle manipulation.
