feat: add Malay BFCL benchmark dashboard

[farhan-helmy]

Summary

PixelSpaceAI now has a public dashboard for the Malay BFCL benchmark. It turns the canonical comparison JSON into a responsive leaderboard, category views, and exact score tables without duplicating benchmark data.

The dashboard build rejects malformed or inconsistent scores before deployment. Pull requests run the same build and headless-browser smoke test, while only main can publish to GitHub Pages.

Validation

• 10 site build and browser tests pass.
• 49 benchmark harness tests pass.
• The built page was opened in headless Chrome at desktop and narrow mobile widths.
• Canonical scores, category selection, and the failed-data error state were verified.
• JavaScript syntax, Python compilation, the production build, and git diff --check pass.

Code review: complete (run_id: 20260819-125300-292cb4aa). All four validated findings were fixed before commit.

Post-Deploy Monitoring & Validation

• Check the Deploy benchmark dashboard workflow for successful build, artifact upload, and Pages deployment jobs.
• Open https://pixelspaceai.github.io/benchmark/ and confirm HTTP 200, 76.54%, ILMU Mini v3.3, and category controls render.
• Healthy signal: the live page uses the current canonical comparison JSON and category links update without console errors.
• Failure signal: a 404, a visible data-load error, stale scores, or a failed Pages job. Re-run the workflow for transient failures; revert the merge if the built artifact is invalid.
• Validation window and owner: immediate post-merge verification by the PixelSpaceAI maintainer.
