Hindsight perf dashboard

Static dashboard rendering perf-test results for vectorize-io/hindsight. Lives on the gh-pages branch of this repo and is served at:

https://vectorize-io.github.io/hindsight-continuous-performance-monitor/

How it works

The hindsight Performance Tests workflow runs perf-test on every scheduled tick (and on push to dev branches), then runs scripts/benchmarks/publish-perf-results.sh which:

1. Enriches the perf-test JSON with commit metadata (subject, author, date, commit URL, PR URL).
2. Clones this repo's gh-pages branch with a PAT.
3. Writes data/<timestamp>-<short_sha>.json.
4. Updates data/index.json (manifest of all runs, newest first).
5. Commits and pushes.

The dashboard pages (index.html, <suite>.html, compare.html) are pure HTML + Chart.js (CDN) + a single assets/app.js ES module — no build step.
