Accepts band names (["A00", "A03"]) or integer indices ([0, 3]), validates input, and passes through to VirtualTIFF's new band_indices parameter. Unselected bands are never fetched from cloud storage — filtering happens at the chunk manifest level before dask tasks are created.

Also makes integration test fixtures self-sufficient by moving download/load into the async fixture so tests can run independently.
