### What problem does this PR solve? Fix memory corruption in PredicateColumnType::insert_duplicate_fields for string types Fixed a bug in the pointer arithmetic when inserting duplicate string values. The original code used dst += i * str.size() which incorrectly multiplied by the loop index, causing: - Iteration 0: no advance (correct by accident) - Iteration 1: advance by 1×size (correct) - Iteration 2: advance by 2×size (wrong - overwrites beyond allocated memory) This resulted in memory corruption and incorrect string data when inserting more than 2 duplicates. The fix changes to dst += str.size() to correctly advance the pointer by one string length per iteration. Added unit tests covering: - String type with multiple duplicate insertions - Integer type duplicates - LargeInt (Int128) type duplicates Introduced by #60530 ==13605==ERROR: AddressSanitizer:
