        <!--
          Paimon OSS/S3 FileIO plugins. These register org.apache.paimon.fs.FileIOLoader
          service providers (paimon-s3 -> S3Loader, paimon-jindo -> JindoLoader) used to read
          object-store-backed Paimon tables (e.g. DLF REST catalogs over OSS). They MUST be
          bundled here, alongside the FileIOLoader interface that lives in paimon-common: when a
          BE-side read resolves the latest snapshot from the filesystem, RESTTokenFileIO.fileIO()
          calls FileIO.get() -> ServiceLoader.load(FileIOLoader.class, FileIOLoader's classloader),
          which eagerly instantiates every registered provider. A provider and the FileIOLoader
          interface it implements must be reachable from the same classloader. These plugins used
          to sit on the shared preload-extensions (JVM app) classpath, which does NOT carry
          paimon-common's FileIOLoader; since JniScannerClassLoader is parent-first, the app-loaded
          S3Loader/JindoLoader could not resolve the child-only interface -> NoClassDefFoundError:
          FileIOLoader. Co-locating them here keeps the whole FileIO SPI in one classloader; the
          assembly's metaInf-services handler merges their service files with paimon-common's
          (local/hadoop) into one complete provider list.
