[I] [Bug] skipFully spins forever on a zero-byte skip at end of stream [paimon]

LuciferYang opened a new issue, #9778:
URL: https://github.com/apache/paimon/issues/9778

   ### Bug description
   
   `HadoopSeekableInputStream.skipFully` (and its copies in every HadoopCompliantFileIO wrapper: azure, cosn, gs, jindo, obs, oss, s3) loops with
   
       while (bytes > 0) { bytes -= in.skip(bytes); }
   
   A blocking stream at end of file returns 0 from `skip`, so a small forward seek — the vectored-read seek helper skips gaps of up to 1 MiB instead of seeking — past a truncated or shorter-than-expected file spins the loop forever instead of failing the read.
   
   ### Expected behavior
   
   Throw `EOFException` when a skip call makes no progress, like Hadoop's own `IOUtils.skipFully` treats premature EOF.
