### Problem When IDENTIFIER FIELDS are set, and `merge-on-read` mode is used, a validation error occurs due to incorrect metadata schema checks. ### Solution Adjusted the `calculateMetadataSchema()` method in `SparkScanBuilder` to avoid validating identifier fields in metadata columns. ### Tests Added unit tests in `TestMergeOnReadWithIdentifierFieldsDelete`、`TestMergeOnReadWithIdentifierFieldsMerge` and `TestMergeOnReadWithIdentifierFieldsUpdate` to validate the fix.
