14mo AssetToAssetSwapHookForERC4626Converts raw ERC20 assets to/from ERC4626 vault wrapper shares in beforeSwap, then executes a nested swap on the corresponding vault wrapper pool via poolManager.swap(), returning a BeforeSwapDelta so users can trade underlying assets directly without manually managing vault shares. Falls back to owner-configured default vault wrappers when no hookData is provided.
