GetStores replaces GetDCFStores: it takes a context, has no count argument and returns a plain slice. GetStore returns the one mounted card, or ErrNoStore or ErrMultipleStores. Each Object keeps the fs.FS its card was read through, and Hash reads through it, so tests can use fstest.MapFS. A cancelled context stops the read before the next directory. Library errors wrap with %w. Model: opus-5-5 Co-authored-by: clawbot <sneak+clawbot@sneak.cloud>
