Summary
WASI VFS directory enumeration functions are not fully implemented, causing os-test dirent and nftw tests to fail. The VFS needs to support fd_readdir properly so that libc functions like readdir(), rewinddir(), seekdir(), scandir(), and fdopendir() work correctly. nftw() (file tree walk) also depends on working directory enumeration.

Expected behavior
All dirent functions should enumerate directory contents correctly through the WASI VFS layer.
Context
Discovered via os-test POSIX conformance suite. Tracked in posix-exclusions.json as fail / implementation-gap.
