feat: add GitHub star nudges across the site

- Prepend attribution comment to "Copy all" exporter clipboard
- Show inline ⭐ Star nudge on individual rule copy (3s, dismisses automatically)
- Change StatsBar stars label to "engineers starred" for social proof
- Add milestone progress bar toward 10k stars in StatsBar
- Fix header/StatsBar showing "0" when SSR GitHub API fetch fails (use "—" placeholder)
