// List files in a directory on an SMB share.
//
// Usage:
//   SMB2_PASS=secret cargo run --example list_directory
//
// Env vars: SMB2_HOST (default "192.168.1.100:445"), SMB2_USER (default "user"),
//           SMB2_PASS (required), SMB2_SHARE (default "Documents").
// Set RUST_LOG=smb2=debug for protocol-level logging.
