Pull Request Overview
This PR refactors the JDBC driver version handling system to properly parse and store major/minor version numbers using bit-shifted integer encoding. The changes address issue #2410 by implementing a new version parsing method that encodes the major version as (major << 16) | minor and uses the patch version as the minor version for JDBC compliance.
- Implemented new
parseVersion()method with bit-shifted encoding for version numbers - Refactored driver version access from public static fields to private fields with getter methods
- Added comprehensive test coverage for version parsing with various version formats

- jdbc-v2/src/main/java/com/clickhouse/jdbc/Driver.java (171-171) The return value of `parseVersion` is confusing - it returns `[majorVersion, patch]` where `majorVersion` is actually an encoded combination of major and minor versions. This makes the method name misleading and the return value hard to understand. Consider returning a more explicit structure like `[major, minor, patch]` or creating a dedicated version class.
