Subject: [PATCH] fix(ci): build website from latest benchmark results

The website job generates charts from results/summary.json on main, but
scheduled Benchmark runs only publish to the `results` branch: benchmark.yml
forces COMMIT_TO_MAIN=false on schedule, so transform-results.yml skips its
"Commit to Main Branch" step. main's copy therefore only updates on a manual
workflow_dispatch with commit_to_main=true.

The last such run was 2025-09-09, so the deployed site has been built from an
11-month-old snapshot. Every framework added since renders with empty charts -
currently Astro, and Gea once it has been benchmarked.

Sync summary/summary.json from the results branch into the build working tree
before generating the site. Nothing is committed, so the existing commit_to_main
policy is untouched; the deploy just stops reading a stale snapshot. Falls back
to the committed file with a warning annotation when the results branch is not
reachable, so forks are unaffected.
