Compound request integration tests: stitch_responses, capture_file_id, inherit_context, CREATE+CLOSE chain

- Add FileAndBuf struct wrapping file + reusable read_buf Vec
- read(): reuse Vec capacity across calls, use unsafe set_len to skip memset
- ~15% read throughput improvement (2.6 → 3.0 GB/s on localhost smbclient)
