Add share-relative directory enumeration with complete pagination, exact Unicode names, observed metadata, entry limits, and explicit access/path errors. Interrupted pages, duplicate names, and failed close do not return a partial list.

Validate 4,004 entries against an independent Linux filesystem oracle, interrupt first/second/tenth request and response pages and close, then reconnect and repeat. Add a reproducible caller-owned VM harness and bounded record/truncation tests.

Validation: four unit tests, one doctest, nine live directory cases, Clippy, and iOS device/simulator linking. Disposable lab removed.
