Fix Hacktoberfest Leaderboard

Fix Hacktoberfest Leaderboard (2025)

Summary

• Restores the hourly-updating Hacktoberfest leaderboard for October 2025.
• Replaces fragile logic with a strict October (UTC) merged window, full pagination, and consistent issue body rendering.

Why

• The previous workflow wasn’t updating because:
  • Missing pull-requests: read permission prevented pulls.list from returning data.
  • Node 16 action (actions/github-script@v6) was outdated.
  • PR window was “last 30 days” (not strictly October).
  • Issue body assembly had inconsistencies in some branches/edits.

What Changed

• uses: actions/github-script@v7 (Node 20).
• Added permissions: pull-requests: read (kept contents: read, issues: write).
• Strict October window (UTC) for merged_at:
  • Oct 1 00:00:00 UTC → Oct 31 23:59:59 UTC.
• Pagination of closed PRs (100/page) with early exit before October.
• Strict size labels only: small | medium | large → 5 | 10 | 15 points.
• Tie-breaker: highest single PR size (small < medium < large).
• Proper template-literal issueBody with rich copy + empty-state fallback.
• Kept token style consistent with repo: github-token: ${{ secrets.GITHUB_TOKEN }}.
• Tracks only block/goose for 2025 (can be expanded later).

Edge Cases / Notes

• Points default to small (5) if none of small|medium|large labels are present.
• Only PRs merged in October (UTC) and labeled hacktoberfest are counted.
• If >100 closed PRs are present, pagination ensures none are missed.
• If no qualifying PRs exist, the issue shows a clear empty-state message.
