beforeInitbeforeAddLiqbeforeSwapswapDelta 1 13mo PhiEthHooksImplements a custom 1:1 exchange between ETH and phiEth (an ETH-wrapper token) by intercepting swaps in beforeSwap: takes input tokens from the PoolManager, converts via phiEth.deposit/withdraw, and settles output — bypassing concentrated liquidity entirely via BeforeSwapDelta. Blocks all direct liquidity additions and only accepts ETH/phiEth pools with zero fee. Base beforeInitbeforeAddLiqbeforeSwapswapDelta 1
