fn owner(env: soroban_sdk::Env) -> soroban_sdk::AddressSwaps the bytecode in place: the address and all storage survive.
new_wasm_hash must already be uploaded — see stellar contract upload.

statement.target before hashing, so an attestation only works for the
contract presenting it; every other field is trusted exactly as passed.
Expiry, replay, uuid or expiration disagreement, and an unregistered
attester return a [RegistryError]. An invalid signature instead aborts
the invocation with Error(Crypto, InvalidInput), which is why no
InvalidSignature variant exists. Neither outcome spends the uuid.
