Add Hibernate 7 batches 2-6: mapping styles, JPA annotations, natural IDs, @Immutable, stored procedures, in-memory test databases, JNDI mocking, proxies, associations, temporal mapping, named queries, HQL, Criteria API and EntityManager bootstrapping (Hibernate 7.4.5.Final + Spring Boot 4.1.1 + JDK 25)

+ * persistence unit -- not just the ones a matching orm.xml entry overrides. OverrideEntity
+ * carries @Id/@GeneratedValue on "id" in Java, but the metadata-complete orm.xml entry only
+ * declares <basic name="value"> and omits <id> entirely. Result: bootstrap fails because
+ * the (ignored) @Id annotation no longer counts -- proving metadata-complete is not just an
+ * override switch, it is a full annotation kill-switch for the persistence unit.
