The Zip64 branch of the streaming header reader assumed a data descriptor always follows a >=4GB entry. When the entry instead has back-patched sizes (no descriptor), the following header was parsed as descriptor fields, overwriting the entry's correct size/CRC with central-directory 0xFFFFFFFF sentinels and, on non-seekable async streams, leaving the reader misaligned so the next entry threw. Now it detects a header signature after the entry data and leaves the already-correct metadata untouched, parsing that header normally. The fix has been applied to both the sync and async readers.
