Fix hybrid-extract multi-part archive + extractor CRC handling

- findReadyArchiveSets: for .part1.rar, require ALL package items
  to be terminal before allowing extraction (prevents premature
  extraction when later parts have no targetPath/fileName yet)
- JVM extractor: remove CRCERROR from isPasswordFailure() — only
  DATAERROR indicates wrong password. CRCERROR on archives where
  7z-JBinding falsely reports encrypted no longer triggers password
  cycling.
- looksLikeWrongPassword: remove CRC text matching, keep only
  explicit "data error" for encrypted archives.
