  --cooldown-secs <n>              Default: 15
  --out-dir <dir>                  Default: target/bench/issue712-deeper-zero-copy-capture-<timestamp>
  --capture-interval-secs <n>      Default: 15
  --capture-prom-metrics-urls <csv>
                                   Default: http://127.0.0.1:8889/metrics
  --capture-rustfs-pid <pid>       Optional explicit rustfs pid
  --dry-run
  -h, --help

Notes:
  - This wrapper assumes the local RustFS server is already running with:
      RUSTFS_ERASURE_ENCODE_BYTESMUT_INGEST=true
  - It reuses scripts/run_put_large_stage_breakdown_with_capture.sh
    and only narrows the matrix to the deeper-zero-copy focus area.
