Uses BeforeSwap and AfterSwap return deltas to capture fees directly from USDC in the swap; owner controls a pause flag and per-pool allowlists.

The afterSwap hook is a no-op that simply returns its selector. Base afterSwap 2 5mo TokenFactoryToken factory that deploys ERC20 tokens with Uniswap v4 pools (1% fee tier), seeding them with 99% of total supply as single-sided liquidity. The afterSwap hook is a no-op; LP fees accumulate in the pool and token creators can claim them via claimLPFees(). Base afterSwap 2 5mo GitlawbAgentHookCharges a configurable output fee (in basis points, max 10%) on each swap and transfers it to a treasury address using afterSwap with afterSwapReturnsDelta. The fee rate and treasury address are mutable by the immutable owner.
