IERC7579Hook

Hook module (type 4): the single global hook that wraps the account's execution surface. preCheck runs before the batch (returning opaque context), postCheck after — letting it enforce arbitrary pre/post-execution policy (spend guards, allowlists, invariants) and revert to block the execution. The wrap is ATOMIC (preCheck(); _execute(); postCheck();, per the ERC-7579 reference): a reverting batch, preCheck, or postCheck reverts the WHOLE call — including any preCheck state effects — so postCheck runs only on an otherwise-successful execution, never after a reverted one.
