### Purpose fix #8516 - `MultisetType` did not override `equalsIgnoreFieldId(DataType)` or `isPrunedFrom(Object)`, so it inherited the `DataType` base methods that just `return equals(o)` and compare element field ids. - For `MULTISET<ROW<...>>` this made ignore-field-id comparison and pruning wrongly return false, corrupting schema-evolution comparison up the chain (`DataField.equalsIgnoreFieldId` / `RowType.equalsIgnoreFieldId`). - Add both overrides recursing into `elementType`, matching sibling `ArrayType`/`MapType`/`RowType`/`VectorType`. ### Tests - Added `MultisetTypeTest` covering positive (differing field ids equal, pruned element) and negative (different name/type) cases for both methods. - `mvn -pl paimon-api test` — MultisetTypeTest 4 tests passed; module `clean install` green (no profiles). -- This is an automated message from the Apache Git Service.
