[HaoyL666]

Summary

Adds eight new generated, controller-backed OCI resources to OSOK:

• Migration in databasemigration.oracle.com/v1beta1
• DrPlan in disasterrecovery.oracle.com/v1beta1
• DistributedDatabase in distributeddatabase.oracle.com/v1beta1
• AgentEndpoint in generativeaiagent.oracle.com/v1beta1
• DataSource in generativeaiagent.oracle.com/v1beta1
• JmsPlugin in jms.oracle.com/v1beta1
• MediaWorkflowConfiguration in mediaservices.oracle.com/v1beta1
• DomainGovernance in tenantmanagercontrolplane.oracle.com/v1beta1

What Changed

• Updated internal/generator/config/services.yaml to include the new resource kinds.
• Generated API types, deepcopy code, CRDs, RBAC, samples, package manifests, and docs for the new resources.
• Added generated controllers and registrations so the new kinds are wired into the manager/package surfaces.
• Added service-manager runtime clients, generated runtime hooks, and focused runtime client tests for each resource.
• Added formal metadata, imports, logic gap docs, and generated diagrams for the new controller surfaces.
• Refreshed validator/error coverage registries and generated coverage baseline data for the expanded resource set.

Validation

• Added/updated runtime client unit tests for all eight new service-manager packages.
• Generated artifacts are included with the branch: CRDs, deepcopy, samples, package manifests, docs, formal metadata, and validator registries.
• repo gates and make test
