Add Latest Key Version Details to GetKeyResponse

New Feature

✨ Extended the GetKeyResponse protobuf message to include two new fields: latest_key_version_id and latest_rotation_time. These fields provide consumers of the GetKey API with the ID of the most recent key version and the timestamp of the last key rotation (in RFC3339 format), without requiring an additional request.

Changes

• proto/plugin/keystore/operations/v1/operations.proto: Added two new fields to the GetKeyResponse message:

  • latest_key_version_id (field 5): The ID of the latest key version.
  • latest_rotation_time (field 6): The timestamp of the latest key rotation in RFC3339 format.

• proto/plugin/keystore/operations/v1/operations.pb.go: Regenerated Go protobuf bindings reflecting the new fields, including updated struct definition, raw descriptor bytes, and two new getter methods — GetLatestKeyVersionId() and GetLatestRotationTime().

• proto/plugin/keystore/operations/v1/operations.pb.validate.go: Updated generated validation code to acknowledge the two new fields (no validation rules applied).

The PR adds two new fields (latest_key_version_id and latest_rotation_time) to the GetKeyResponse message. The changes are consistent across the .proto source, the generated .pb.go file, and the generated validation file. The main concern is the use of a raw string for latest_rotation_time instead of google.protobuf.Timestamp, which provides no type safety or structured validation for the documented RFC3339 format.
