AssetToAssetSwapHookForERC4626

UnichainRegistered

Periphery hook for pools using ERC4626 vault wrapper tokens. In beforeSwap, converts input ERC20 assets to vault wrapper shares, performs a nested swap in the corresponding vault wrapper pool via poolManager.swap(), then redeems output shares back to underlying assets. Handles both exact-input and exact-output swaps. Vault wrappers can be supplied via hookData or configured as per-pool defaults by the owner.
