expected behavior: error about multiple statements in query
rustsql do this

this is silent critical logic error

Start by running the reproduction shown in main.rs with the dependency versions in Cargo.toml, then inspect how conn.execute handles the SQL string containing INSERT and UPDATE statements. Done means the multiple-statement call returns an error instead of silently reporting success; verify the behavior with the provided assertions.
