- Add benchmarks/reports/REPORT_TEMPLATE.md — template with __MARKER__
placeholders for all auto-populated fields (latency, throughput,
percentiles, cache delta, benchstat block, environment, ONIX version)
- Add benchmarks/tools/generate_report.go — reads latency_report.csv,
throughput_report.csv, benchstat_summary.txt and run1.txt metadata,
fills the template, and writes BENCHMARK_REPORT.md to the results dir.
ONIX version sourced from the latest git tag (falls back to 'dev').
- Update run_benchmarks.sh to call generate_report.go after parse_results.go;
also derive ONIX_VERSION from git tag and pass to generator
- Update README and directory layout to reflect new files and workflow
