feat: Priority Rebalancer — re-score issues from pipeline data (#174)

Monthly pipeline tool that:
- Reads knowledge store, metrics, and staleness data
- Scores all open issues across the org
- Suggests priority upgrades/downgrades based on accumulated signals
- Generates JSON + markdown reports
- Optional --apply mode to push changes via Gitea API

Signals detected:
- Stale/missing knowledge entries
- Empty knowledge store
- Missing metrics output
- Low repo coverage
- Issue age, activity, assignment status
- Keyword/label analysis

Usage:
  python3 scripts/priority_rebalancer.py --org Timmy_Foundation
  python3 scripts/priority_rebalancer.py --org Timmy_Foundation --apply
  python3 scripts/priority_rebalancer.py --org Timmy_Foundation --json

23 tests, all passing.
