A selection read (a hyperslab or points covering at most half the dataset) decoded each chunk it overlaps into fresh buffers, one per filter stage; it now uses the thread's chunk-decoding scratch like the full readers. Covered by tests/chunked_read_paths_interop.rs (small hyperslabs and points over every filter and type) and the partial-read equivalence tests.
