  1. Upgrade ClickHouse JDBC driver from 0.3.2 to 0.9.6 

    The old driver (ru.yandex.clickhouse:clickhouse-jdbc:0.3.2) failed to
decompress error responses from the server, throwing
"Magic is not correct" IOException instead of reporting the actual
ClickHouse error message. This caused SQLancer to treat expected errors
(like ILLEGAL_TYPE_OF_ARGUMENT) as assertion failures, because the
JDBC exception message didn't contain the expected error substrings.

Changes:
- Update Maven dependency from ru.yandex.clickhouse:clickhouse-jdbc:0.3.2
  to com.clickhouse:clickhouse-jdbc:0.9.6 (with "all" classifier)
- Update all imports from com.clickhouse.client.ClickHouseDataType
  to com.clickhouse.data.ClickHouseDataType (package was renamed)
- Add "Magic is not correct" to expected errors as safety net
