   I think Spark should explicitly block DELETE / UPDATE / MERGE on 
merge-engine = first-row tables.
   Allowing these operations violates first-row semantics and can lead to 
silent data correctness issues due to CoW rewrites producing L0 files that 
shadow valid records.  Failing fast here would align Spark behavior with Flink 
and protect users from unexpected results.
