Includes SessionResolver and ThreadLocalSessionResolver (new interfaces/classes
introduced by the O(M+N) scaling refactor), plus updates to AbstractDatastore,
AbstractMappingContext, and related core classes that the datastore modules
(SimpleMap, Hibernate 5/7) depend on at compile time.

Missed from initial clean rebuild commit.

During child datastore construction, GormRegistry.registerEntityDatastores
calls getDatastoreForConnection() before the parent's datastoresByConnectionSource
map is populated, throwing ConfigurationException for multi-datasource setups.

H5 anonymous child: add self-reference check so the child returns itself when
asked for its own connection name, rather than delegating to the parent map.

H7 ChildHibernateDatastore: use PARENT_HOLDER ThreadLocal to pass the parent
reference through the super() call before the parent field is assigned; also
pass the parent's datastoresByConnectionSource map to HibernateGormEnhancer
so it can resolve sibling datastores during initialize().

Fixes DataSource not found for name [secondary/schemaA] ConfigurationException
in multi-datasource and schema-per-tenant multi-tenancy test suites.

The O(M+N) GormRegistry refactor exposed two classes of regression in
multi-tenancy and multi-datasource scenarios. This commit addresses both.

Production fixes:

GormApiResolver: Move the DISCRIMINATOR mode check before the
MultipleConnectionSourceCapableDatastore delegation so that tenant IDs are
never mistaken for datasource connection names. For the DEFAULT qualifier,
return the preferred (active-transaction) datastore directly rather than
re-routing through getDatastoreForConnection, which would return the parent
and mismatch the session factory already bound to the transaction.

GormRegistry.registerEntityDatastores: Stop overwriting child datastores with
the parent for non-DEFAULT qualifiers that resolve back to the parent. In
SCHEMA and DISCRIMINATOR mode the qualifier is a runtime tenant ID, not a
datasource name; routing it back to the parent is correct and must not clobber
the child entries added by addTenantForSchemaInternal.

GormRegistry.findTransactionManager: Fall back through the full apiResolver
when getDatastore returns null so that DISCRIMINATOR/SCHEMA tenant IDs still
resolve to a transaction manager.

HibernateDatastore (H5) / ChildHibernateDatastore (H7): Return null instead
of throwing ConfigurationException when getDatastoreForConnection is called
for a sibling that is not yet registered during initialization. GormRegistry
will re-register all entities with the correct datastores once initialization
completes. Child datastores also delegate to the parent for unrecognized
connection names so the lookup chain stays consistent.

HibernateGormInstanceApi (H7): Always resolve the template via the datastore
registry rather than caching a DEFAULT-qualifier instance, so that
preferred-datastore switching in multi-datasource transactions picks up the
correct session factory.

GrailsHibernateTransactionManager (H7): Remove debug System.err.println
statements left over from investigation.

Test infrastructure fixes:

gradle/hibernate5-test-config.gradle, gradle/hibernate7-test-config.gradle:
Set forkEvery = 1 so each test class runs in its own JVM. The root
test-config.gradle uses forkEvery = 50 (CI) / 100 (local) for speed; with a
shared GormRegistry singleton that per-test setup/teardown mutates, TCK specs
running before PartitionedMultiTenancySpec in the same JVM were clearing
datastoresByQualifier["default"], causing a NullPointerException in count()
when PartitionedMultiTenancySpec later resolved a GormPersistentEntity. forkEvery = 1
eliminates cross-class singleton contamination at the cost of extra JVM
startup overhead, which is acceptable given the test isolation requirement.

GrailsDataHibernate5TckManager: Add grailsConfig field and populate a local
ConfigObject from it in createSession(), fixing MissingPropertyException when
test specs assign grailsConfig before calling setup().

Verified: H5 669 tests / 0 failures, H7 2960 tests / 0 failures.

…saction routing

    - GormEnhancer: Remove generic type parameters (`<D>`) from deprecated API lookup methods (`findStaticApi`, `findInstanceApi`, `findValidationApi`). This fixes a `MissingMethodException` encountered
  when older compiled code or dynamic Groovy proxies call these methods without exact signature matches.
    - TransactionalTransform: Fix `IllegalStateException: No GORM implementations configured` in multi-tenant environments. Revert logic that incorrectly passed `tenantId` as a connection source
  qualifier to `GormRegistry`, and instead fetch the tenant-specific datastore using `getTargetDatastore().getDatastoreForTenantId(tenantId)`.
    - ServiceTransformation: Ensure the stateful `$datastore` field is properly generated for generic data services to resolve injection failures in tests.
