/**
 * Regression test for GitHub issue #24007
 * https://github.com/oven-sh/bun/issues/24007
 *
 * Issue: Bun's glob/readdir functionality failed on bind-mounted paths in Docker
 * because certain filesystems (sshfs, fuse, NFS, bind mounts) don't provide d_type
 * information in directory entries (returns DT_UNKNOWN).
 *
 * Fix: Added lstatat() fallback when d_type is unknown, following the lazy stat
 * pattern from PR #18172.
 *
 * See also: test/cli/run/glob-on-fuse.test.ts for FUSE filesystem testing.
