Weekly Article Generation Flow

3. Quality check — score ≥ 70/100 before proceeding (see scoring below)
4. Save draft to article-YYYY-MM-DD.md
5. Mark topic as used in article-topics.json
6. Log article to article-log.json
7. Open browser to Substack new post editor for final review
8. Notify via Telegram — "Draft ready at [path] — please review before publishing"

If all topics are used: notify user to add new topics, then exit.
