[compat-canary] Hibernate adapter breaks against latest Hibernate ORM

The weekly compatibility canary failed building/testing the Hibernate adapter against the latest released Hibernate ORM.

This is an early warning that an upcoming Hibernate ORM version introduces a breaking change (API/class relocation, removed method, etc.) before a customer hits it. See the failing run for the exact error:

https://github.com/awslabs/aurora-dsql-orms/actions/runs/33364725555

Stable releases are unaffected — the supported pinned version still builds. Resolve by updating the adapter for the new Hibernate ORM version, then this issue can be closed (the canary will reopen it if the break recurs).

Start with the failing compatibility canary run at https://github.com/awslabs/aurora-dsql-orms/actions/runs/33364725555 and inspect its exact build or test error for the Hibernate adapter. Trace that error to the adapter entry point and update it for the latest Hibernate ORM release. Done means the adapter builds and tests successfully against the new version while stable pinned releases remain unaffected.
