generate CSV/PNG/SVG outputs focused on mixed/RT p95, p99, and max latency.

Options:
  --schedulers "LIST"       Space-separated scheduler list
                            Default: "${DEFAULT_SCHEDULERS}"
  --results-root DIR        Root directory for timestamped results
                            Default: ${RESULTS_ROOT}
  --results-dir DIR         Write this run into DIR instead of the default timestamped path
  --keep-results N          Keep only the newest N result directories (default: 3)
  -h, --help                Show this help
