Review Comment:
   Optional (non-blocking): `CheckTableExists` now propagates `isTableDir` errors, while `ListTables`/`ListNamespaces` intentionally swallow permission errors via `isTableDirForListing`. That strict-vs-tolerant split is defensible, but a one-line comment here explaining the distinction would save the next reader a double-take.
