updateDatasetExamples

Updates multiple existing examples in-place on DRAFT. Validation: All examples are validated against the dataset's schemaType before any writes occur. If any example fails validation, the entire batch is rejected with ValidationException — no examples are updated (all-or-nothing semantics). Asynchronous: Operates in-place on DRAFT. No version bump occurs. Use CreateDatasetVersion to publish DRAFT as a new numbered version. Fails with ResourceNotFoundException if any exampleId does not exist in DRAFT. To add new examples, use AddDatasetExamples instead. State guard: Returns ConflictException (DATASET_NOT_READY) if the dataset status is not in {DRAFT, ACTIVE}. Request size limit: Max 5 MB total request body. Max 1000 examples per call.
