fix: prevent duplicate PRs — pre-flight check and cleanup tools (closes #1460)
Issue #1460: I keep creating duplicate PRs for issue #1128 (7 duplicates!).

Scripts added:
- scripts/check_duplicate_pr.py: Pre-flight check before creating PR.
  Exit 1 if duplicate exists, exit 0 if safe. Use before git push.
- scripts/cleanup_duplicate_prs.py: Close all duplicate PRs for an issue
  except the newest. Supports --dry-run.

Usage:
  # Before creating a PR:
  python3 scripts/check_duplicate_pr.py --repo Timmy_Foundation/the-nexus --issue 1460

  # Clean up duplicates:
  python3 scripts/cleanup_duplicate_prs.py --repo Timmy_Foundation/the-nexus --issue 1128 --dry-run

Status: All 7 duplicate PRs for #1128 already closed. Prevention tools in place.
