feat: implement TurboQuant upstream watch monitoring system

- Add scripts/upstream_watch.py for monitoring upstream repositories
- Add .github/workflows/upstream-watch.yml for weekly automated monitoring
- Add docs/upstream-watch.md for documentation
- Add scripts/run_upstream_watch.sh for easy execution
- Add scripts/test_upstream_watch.py for testing

Addresses issue #15: [P4] Upstream llama.cpp / Ollama TurboQuant watch

Features:
1. Monitor llama.cpp, Ollama, and ggml repositories
2. Search for TurboQuant/PolarQuant/QJL keywords
3. Check issues, PRs, and release notes
4. Generate text and JSON reports
5. Weekly GitHub Action for continuous monitoring
6. Automated issue creation when findings detected

Usage:
- Run monitor: python3 scripts/upstream_watch.py --days 30
- JSON output: python3 scripts/upstream_watch.py --format json
- Weekly monitoring: GitHub Action runs every Monday at 9:00 AM UTC

When upstream lands:
1. Detection: Monitor will detect mentions
2. Evaluation: Compare upstream vs fork
3. Decision: Migrate if upstream is better

Closes #15
