Closes #
Unit and integration tests covering the common scenarios were added
A human-readable description of the changes was provided to include in CHANGELOG
For significant changes, documentation in https://github.com/ClickHouse/clickhouse-docs was updated with further explanations or tutorials

Note

Adds comprehensive JDBC mappings for previously unmapped ClickHouse types to prevent NPEs and improve metadata/class resolution.

Extends JdbcUtils mapping: adds BFloat16, Decimal256, Geometry, UUID, IPv4/IPv6, multiple Interval*, JSON, Object, LowCardinality, Nullable, SimpleAggregateFunction, AggregateFunction, Variant, Dynamic, QBit; changes Map to JDBCType.OTHER; maps UUID to UUID.class in Java class map
Updates metadata expectation: Map columns now report Types.OTHER
Adds integration tests for arrays of UUID, arrays of IPv4/IPv6 (including Nullable(IPv6)), and arrays of Map(String, Int32); unit test ensures every ClickHouseDataType has a Java class mapping
