### Purpose fix #8515 - `FunctionChange.UpdateDefinition.hashCode()` returned `Objects.hash(definition, definition)`, hashing `definition` twice and omitting `name`. - Its `equals()` compares both `name` and `definition`, so unequal objects (same `definition`, different `name`) collided into one hash bucket, violating the equals/hashCode contract. - Fixed to `Objects.hash(name, definition)`, matching the sibling `AddDefinition.hashCode()` in the same file. ### Tests - Added `FunctionChangeTest#testUpdateDefinitionHashCodeIncludesName` (same definition, different name -> different hashCode) and `#testUpdateDefinitionEqualsHashCodeConsistency` (equal objects -> equal hashCode), plus `#testAddDefinitionHashCodeIncludesName`. - `mvn -pl paimon-api clean install` — all tests passed (FunctionChangeTest: 3 passed). -- This is an automated message from the Apache Git Service.
