Subject: [PATCH] test(09-01): add directory test cases to Kotlin
 cross-validation script

- Test 6: nested directory extraction (3+ levels deep, 4 files)
- Test 7: empty directory creation without decryption errors
- Test 8: mixed standalone files + directory pack/unpack
- All 5 original test cases preserved unchanged
