[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/34091472641

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 GitHub Actions run 34091472641 and inspect the exact Hibernate ORM build or test error. Then locate the Hibernate adapter entry point implicated by that failure and compare it with the latest ORM API. Done means the adapter builds and tests against the new Hibernate ORM version while the stable pinned version remains unaffected.
