Pull request overview
This PR refactors H2 database compatibility mode handling by introducing an enum-based approach to replace the previous dialect-based system. The changes enable better support for H2's Regular (native) mode and improve mode detection from both JDBC URLs and active connections.
Key changes:
- Introduced
H2.Modeenum to represent H2 compatibility modes (Regular, MySQL, PostgreSQL, MSSQLServer, MariaDB) - Refactored mode detection to query the active H2 connection's
INFORMATION_SCHEMA.SETTINGS - Added comprehensive tests for all supported H2 modes and unsupported mode error handling
